3 About CarboQC and PFD Filling

Device

CarboQC uses the patented "Multiple Volume Expansion" (MVE) method toeliminate the influence of dissolved air on the determined carbon dioxide content.

The analysis is based on highly accurate absolute pressure and temperature

measurements.

CarboQC can determine the CO2 content of sugar based soft drinks, soft drinks

with low sugar concentration, diet drinks, beer, strong beer, sparkling wine and

mineral water.

CarboQC can be used in a laboratory environment as well as at-line. For at-line

measurements, a special protective casing is available.

The instrument is equipped with rechargeable batteries to provide the required

power for a limited period of time.

To perform a measurement, connect the instrument to the PFD Filling Device in

the laboratory or to a production line or tank, select the proper method, and press

the <Start> key. Within approx. 2 minutes the CO2 concentration is shown on the

display and transferred to the data memory. The measuring result can also be

printed out immediately or later from the data memory.

6 Putting CarboQC into Operation

20 C26IB001EN-B

If the battery has to be exchanged by an authorized service technician, make sure

that the battery service is performed, even if the newly installed battery is fully

charged.


6.1 Instal ling CarboQC

CarboQC can be used in the laboratory as well as at-line. In any case, sample

has to be transferred into the measuring chamber of CarboQC without the loss of

carbon dioxide during the transfer. Subsequently, the installation of CarboQC in

combination with a PFD Filling Device is described.

The PFD Filling Device pierces the bottle closure or the base of the can and

forces the beverage into the measuring chamber of CarboQC using compressed

gas (6±0.5 bar relative/87±7 psi). In the unlikely event that a bottle or can bursts,

the operator is protected by a safety shield which is moved vertically over a bottle

or can. A safety pin on the bottom of the safety shield ensures that the system

cannot be pressurized as long as the safety shield is not in the protective position.

WARNING

If a glass bottle bursts inside the PFD, the safety shield protects the user from

glass chips. However, some small glass particles may still be released by therear gap of the safety shield which could lead to injuries of eye or face.



• If a container bursts, chippings may be hurled through the gap on the backof the PFD Filling Device. Therefore place the PFD Filling Device with adistance of 0.5 m (20 inches) with its back to the wall. The PFD FillingDevice has to be placed so nobody can stand between the PFD FillingDevice and the wall.

WARNING

Compressed gas is used. Loose hoses may lead to injuries, especially of eyes

and face.

• If CarboQC is operated in combination with a PFD Filling Device, do notactivate the compressed gas supply before all hoses are properlyconnected.

NOTICE

• Do not operate CarboQC without the filter being installed.

• Do not place CarboQC on a wet or humid bench because humidityentering the housing could damage the instrument.




C26IB001EN-B 21

TIP If required, fasten the PFD Filling Device to the bench with clamps using the

opening in the front of the base plate or with a bolt through the corresponding hole

in the base plate.

Compressed gas supply

CarboQC and PFD Filling Device are best operated with compressed air. In case

a dissolved oxygen meter is also connected, use compressed nitrogen as

compressed air might influence the oxygen result.

If there is no in-house supply of compressed gas available, the PFD Filling Device

can also be operated with compressed gas from a gas cylinder.

The hoses of the PFD Filling Device have an outer diameter of 6 mm. If the

compressed gas outlet does not match the required diameter for PFD Filling

Device operation, check for pressure adapters at your local supplier.

Mounting the hoses

For the hose connections between CarboQC and PFD Filling Device, use the

delivered polyurethane hose 2.5 x 4 mm.

To connect a hose

• To connect a hose to a fitting, push the hose into the fitting as far as it will go.

TIP When reconnecting a hose, cut off a few millimeters of the hose if the color of the

hose is changed to achieve tight seal.

To disconnect a hose

• To remove the connection, press the ring of the fitting towards the fitting andthen pull out the hose.

NOTICE

Keep the hoses between the instruments as short as possible. This reduces

sample consumption as well as the risk of CO2 diffusing through the hoses

thus influencing the results.

NOTICE

Only take apart connections if it is really necessary to do so as frequent

handling may destroy the fitting.

8 Measurement

8.1 Preconditions

CarboQC determines the amount of dissolved carbon dioxide in a beverage. To

get a correct measurement, the instrument has to be in good working condition

(see Chapter 9.2).

In addition, the sample package has to be in equilibrium. As carbon dioxide in a

package can be found in the liquid phase as well as in the head space,

equilibration is essential for repeatable and well defined measurement results.

Equilibration can be achieved by gently shaking the bottle horizontally about 15

times back and forth. This will ensure that the net transfer of CO 2 between liquid

and head space is zero, in short, in equilibrium.

8.2 Preparing CarboQC

CarboQC is equipped with 7 standard methods to account for the different

solubility of carbon dioxide in different beverages (see Chapter 14.1.1). The

selected method is displayed in the top left corner of the display and has to be

selected manually prior to a measurement by pressing the <Method> key,

selecting the desired method and confirming with <Enter>.

If necessary, press <Method> on CarboQC to select the appropriate method for

the sample to be measured from 7 standard methods or 17 customer-specific

methods. For customer-specific methods, see also Chapter 14.

The 7 standard methods are:

The standard methods do not compensate for any temperature effect that

influences the CO2 distribution between headspace and liquid of the bottles or

cans. Therefore, they should only be applied within a small range (e.g. 3 °C/5 °F

around reference temperature) of package temperatures.

8 Measurement

C26IB001EN-B 27

Compensation of the headspace-related temperature effect and therefore

measurements in a wider range of package temperatures can be achieved with

the 17 customer-specific methods once they are properly set up. For more

information, see Chapter 12.2.5.

8.3 Transferring the Sample into the Measuring

Chamber

Sample transfer always carries the risk of loss of carbon dioxide or introduction of

other dissolved gases. Thus, sample transfer is best performed in combination

with a filling system that avoids these risks.

The PFD Filling Device is equipped with a seal to close off a small area of the

package, bottle or can. This small area is pierced with a knife to allow introduction

of a sample tube.

Applying pressurized gas to the head space of the container allows the transfer

of sample to the CarboQC measuring chamber without the loss of CO 2.

Subsequently, the measurement of CO2 with CarboQC in combination with a PFD

Filling Device is described in detail.

TIP Piercing the package with a PFD Filling Device might result in the pierced disk

falling into the container. The filter between PFD Filling Device and CarboQC will

keep this particle from entering the measuring chamber.

8.4 Measurement Using the PFD Filling Device

8.4.1 Setting the Correct Flow

The flow through the measuring chamber should be such that 100 to 150 mL of

sample are consumed when the filling time is set to 20 seconds. Considerably

lower or higher flow rates may cause erroneous measurements due to sample

carry-over or gas bubbles in the measuring chamber.

Fig. 8 - 1 Measuring chamber and flow valve

8 Measurement

28 C26IB001EN-B

To adjust the flow, insert a suitable tool (e.g. screwdriver, ... ) into the cavity of the

flow valve and turn it clockwise for decreased and counterclockwise for increased

sample flow.

With a graduated vessel

1. Use a beaker or graduated cylinder to check the correct flow.

2. Insert the T-hose connector of the sample outlet hose into the beaker.

3. Select the menu "instrument > rinse" and set the rinsing time to 20

seconds.

4. Position the flow valve (see Fig. 8 - 1) at about 10% flow, i.e. close to the

minimum flow position.

5. Carry out a measurement as described in Chapter 8.4.2.

6. Check the volume of liquid consumed: It should be 100 to 150 mL.

7. If the volume is not in the required range, slightly open or close the flow valve

(see Fig. 8 - 1) and repeat steps 5 to 7 until the volume/weight is within the

required range.

With a marked bottl e

1. Make volume markings "0" and "150 mL" on a transparent 0.5 L (16 oz) or

similar size PET bottle.

Use water and a graduated cylinder or a balance to correctly place thesemarkings on the bottle.

2. Fill the bottle up to the "0" mark with deionized water and close it.

3. Insert it into the PFD Filling Device.

4. Perform steps 3 to 7 as described above.

Via weighing

1. Weigh a full beverage bottle or can and make a note of the weight.

2. Insert the package into the PFD Filling Device.

3. Perform steps 3 to 5 as described above.

4. Remove the package from the PFD Filling Device and weigh it again.

The weight should have decreased by 100 to 150 g.

At CarboQC

1. Press <Start> to start the measurement.

The measuring chamber is first rinsed and filled with 100 to 150 mL of the

new sample.

2. Check the measuring chamber visually for bubble-free sample flow.

It must be free of bubbles before the actual analysis starts. If the bubbles donot disappear after approx. 15 seconds, clean the filter (see Chapter 10.3).

3. Check the pressure of the compressed gas supply. It shall be 60.5 bar

relative (877 psi).

Once the rinsing is finished, the analysis will start. The piston will move downto a first halt and then to a second halt with the stirrer permanently inoperation.

4. Wait approx. 90 seconds for the measurement result.

The measurement result will be displayed, stored in the memory andoptionally printed out. The piston will then move up, but the measuringchamber will remain closed.

TIP If a measurement was carried out with an incorrect method, the current result can

be recalculated using the correct method as long as this result is still displayed.

Press <Method>, select the correct method and press <Enter>. The recalculated

8.5 Checking for a Correct Measurement Procedure

and Avoiding Errors

Zero point checks

Regular zero point checks of CarboQC with deionized water are recommended

to survey faultless functionality of the instrument. The water check with CarboQC,

when carried out correctly with deionized water, is the precondition for a correct

measurement result. The result has to be 0± 0.02 vol (0± 0.03 g/L).

If the zero point check and adjustment are carried out with water that contains

CO2, the consequence will be an unjustified offset. Consequences are systematic

errors of results.

Sample equilibration

Only transfer equilibrated sample to the measuring chamber of CarboQC. If

samples are not equilibrated (shaken) prior to analysis, the consequence might

be erroneous results or poor repeatabilities.

Correct measurement method

Check whether the correct measuring method is chosen on CarboQC. A wrong

method will lead to a wrong result.

Correct sample flow

Check the correct flow. The volume consumption per measurement is

recommended to be 120 to 150 mL, and for identical samples at least 100 mL.

Too low sample volume consumption causes sample carry-over.

Correct filling pressure

The filling pressure displayed on the CarboQC display has to be 5.5 to 6 bar

relative (79 psi to 87 psi) and the measuring chamber has to be filled without

bubbles. Too low sample pressures during sample filling causes bubbles in the

sample chamber. As a consequence, the starting volume will consists partially of

gas bubbles thus yielding incorrect results.

Measuring chamber filled without bubbles

Bubbles in the measuring chamber can falsify the result. The most common

cause for bubbles is a clogged filter. To clean the filter, see Chapter 10.3.



9 Checking the System

34 C26IB001EN-B


9.1 Influencing Factors

Mechanical functionality of CarboQC is essential for a correct result. CarboQC

has three parameters that act as a precondition for a correct result.

• pressure• temperature• volume expansion of the measuring chamber

9.2 Zero Point Check

A zero point check is necessary before starting the determinations. The zero pointcheck is a measurement with deionized (or distilled) water. The CO2 result has to

be 0±0.02 vol (0±0.03 g/L).

The deionized water must not contain any dissolved carbon dioxide and is ideally

free of ions such as calcium that could cause deposits in the measuring chamber

of CarboQC.

Sometimes, deionized water contains CO2 absorbed from the ambience and

CarboQC displays the amount of the CO2 absorbed. Either heat up and boil the

water and cover it up while cooling down or do the water check with tap water. In

case of using tap water, rinse the measuring chamber with deionized waterafterwards.

In case the measurement of deionized water does give a CO 2 reading out of

tolerance, always check the water first before inserting a pressure offset (see

Chapter 9.5) into CarboQC.

In general, the zero point check with CO2-free water is sufficient to ensure correct

functioning of the instrument in-between service intervals.

9.3 Check with Carbonated Liquid

Sometimes checkups are required with test samples at elevated carbon dioxide

contents. Usually these checkups are provided within the periodical service and

maintenance procedure. In case more frequent tests are required, continuous

surveillance can be performed on a day-to-day basis.

There are two ways to perform an instrument check with carbonated liquids.

The first is the use of a CO2 standard. This procedure shall only be carried out by

an authorized Anton Paar representative or service technician.

The second is the use of a control chart and internal standards.




C26IB001EN-B 35

Cans of diet soft drink or other cans of a non-sucrose based, non-inverting soft

drink with > 3 vol (6 g/L) CO2 content are suitable to be used as internal

standards.

If filling cans, provide 36 cans for initial preparation of the standards plus a

sufficient number of cans for one check measurement per day over the time span

between instrument calibrations by Anton Paar service representatives. Only use

cans from the same production minute(s).

If purchasing cans, make sure that the required number of cans is from the same

batch.

To p repare in ternal standards

1. Immediately after calibration of CarboQC by an Anton Paar service

representative, draw 6 cans from the beginning, 6 cans from the middle, and

6 cans from the end section of a production run and measure them.

2. Calculate the mean values for every 6 measurements for the beginning,

middle and end sections.

The 3 mean values may only differ by ±0.02 vol (±0.04 g/L).

3. If the mean values are suitable, provide a sufficient number of cans from this

production run to be kept as internal standards.

4. If the mean values are not suitable, measure another 3 times 6 cans as

above.

5. Determine the 3 mean values of the 12 respective measurements (for each

mean value take the 6 measurements from the first selection plus the 6

measurements from the second selection).

These 3 mean values may only differ by ±0.015 vol (±0.03 g/L).

6. If the mean values are suitable, provide a sufficient number of cans from this

production run to be kept as internal standards.

7. If the mean values are not suitable, the cans are not suitable as internal

standards and cans from a different, more stable production run have to be

used.

NOTICE

Only use cans as internal standards. Do not use bottles as their CO2 content

might change.




36 C26IB001EN-B

To draw and use the cont rol chart

1. Calculate the mean m and standard deviation sd of all 18 (or 36)

measurements.

The standard deviation shall be 0.025 vol (0.05 g/L) maximum based on theabove limitations.

2. Draw a control chart with sample number on the x-axis and CO2

concentration on the y-axis ranging from (m - 3 * sd) to (m + 3 * sd) as the

control limits.

3. Draw control limit lines, mean line and auxiliary lines as appropriate. This

can either be done on paper or using a suitable computer software.

4. Measure one can of the internal standards per production day and draw a

corresponding point in the control chart.

5. If a clear trend away from the mean becomes visible over time or the control

limit of 3 * sd is exceeded successively, call for service immediately.

9.4 Beginning of the Shift /Day

C26IB001EN-B 37

9.5 Entering a Pressure Offset

With the menu "auto p-offset" , an offset for the pressure sensor can be

determined semiautomatically. Enter a pressure offset if the CO2 result of a zero

point check with deionized water is out of specification (see Chapter 9.2).

TIP Sometimes, deionized water contains CO2 which has been absorbed from the air,

and this CO2 content is displayed. Before carrying out an automatic pressure

offset, make sure that the displayed CO2 is not caused by the water, but by the

pressure sensor. Boiling and cooling the water before measurement will eliminate

dissolved CO2.

Example:

A zero point check with deionized water yields (even after cleaning the system) a

CO2 value of 0.05 g/L. The maximum allowed deviation for deionized water is 0.03

g/L. Therefore, the pressure sensor must be adjusted:

1. Select the menu "adjustment > auto p-offset" .

In the first line, the previously measured CO2 value (0.05 g/L) is displayed. In

the second line, the pressure value is displayed (e.g. +0.020 bar).

2. Press <Enter>.

The displayed CO2 value flashes.

3. Change the CO2 value using the <> and <> keys until the value is insidespecification (0 ±0.03 g/L).

The pressure value is changing corresponding to the CO2 value.

4. When the required CO2 value is displayed, press the <Enter> key.

The newly calculated pressure offset is automatically stored in the CarboQCmemory and is used for subsequent measurements.

5. To change to the measuring window, press <ESC> three times.

11.1 Using CarboQC with Protective Casing

11.1.1 Overview

The protective casing for CarboQC is especially designed for use in harsh

process environments. The robust polyurethane casing protects CarboQCagainst mechanical impact and splash water. Special foam parts inside the casing

dampen mechanical shocks on the instrument if the instrument falls down or

bumps into an obstacle.

The protective casing is mounted and dismounted fast and easily. The most

important standard tasks during a measurement can be carried out using the keys

on the protective casing:

• switching the instrument on and off • selecting a method• starting and stopping a measurement

11.2 Using CarboQC without Protective Casing

11.2.1 Connecting CarboQC to the Production Line or Tank

TIP If CarboQC is frequently used for at-line measurements at different locations, we

recommend equipping CarboQC with a protective boot (Mat. No. 90079) for

protection of the instrument during transport.

CarboQC can be connected to the line via filter or filter with male hose filling

nozzle (at-line adapter, Mat. No. 18829). This at-line adapter allows for thicker

diameter hoses between adapter and line (see Fig. 11 - 5).

TIP For at-line measurements, keep the hoses between the line and the filter as short

as possible to reduce pressure drops and minimize the risk of the sample

outgassing. The correct flow direction is marked with an arrow.

1. See also Fig. 11 - 6: Connect the outlet of the line/tank to the filter inlet or the

inlet of the at-line adapter or standard filter.

2. Connect the outlet of the filter to the inlet of CarboQC using a polyurethane

hose 2.5 x 4 mm.

3. Connect a polyurethane hose transparent 2.5 x 4 mm to the outlet of

CarboQC.

4. Place the other end of this hose in the waste vessel.

WARNING

Serious injuries through high voltage at instrument parts possible.

• The power supply is not suitable for operation under wet at-lineconditions.

• Charge the battery of CarboQC only under dry indoor conditions.• If CarboQC is not used for extended periods of time (> 2h), store the

instrument under dry indoor conditions only.

WARNING

Operation under pressure. Serious injuries and damage of goods possible if

the maximum allowable pressure is exceeded.• Do not operate CarboQC with sample pressures higher than 10 bar (145

psi) absolute.

NOTICE

Do not place CarboQC on a wet or humid bench because humidity entering

the housing could damage the instrument.




C26IB001EN-B 49

TIP A carrying strap (Mat. No. 16012) is optionally available for safe and convenient

operation under at-line conditions.

Setting the correct flow

To set the correct flow, use the PFD Filling Device and proceed as described in

Chapter 8.4.1.

11.2.2 Measurement

TIPThe minimum pressure for at-line operation of CarboQC has to be 0.5 bar (7.2 psi)above saturation pressure of the dissolved gases. Proper functioning is best

determined by practical tests.

2. If necessary, change the sample number by pressing the <Sample> key.

3. Open the sample valve of the line or tank.

4. Start the measurement by pressing the <Start> key on CarboQC.

5. Watch the measuring chamber.

After approx. 15 seconds rinsing time it should be free of bubbles.

TIP If the system pressure of the line is too low, the measuring chamber will not be

free of bubbles in time. Fill the measuring chamber of CarboQC manually by

pressing the <Rinse> key before pressing <Start>. After the measuring chamber

opens,

• press the <Rinse> key periodically to turn the stirrer on and off,

• make sure that a minimum of 100 mL flows through the measuring

chamber,

• make sure the measuring chamber becomes free of gas bubbles.The measuring result is automatically displayed after approx. 90 secondsand stored in the memory of CarboQC (max. 99 measuring results).

13 Technical Background

C26IB001EN-B 61

13 Technical Background

The working principle of CarboQC is based on the Multiple Volume Expansion

Method and allows the determination of the true CO2 content.

Fig. 13 - 1 shows the principle of the Multiple Volume Expansion method for

eliminating the influence of dissolved air or nitrogen on the measuring result: The

CO2 content is measured at two different volume expansions of the measuring

chamber, i.e. at 10 and 30%. If the two results are identical, there is no dissolved

air or nitrogen present and therefore no correction is required. Dissolved air or

nitrogen makes the second result lower than the first. The difference between the

two results is used to calculate a correction which completely eliminates the

influence of dissolved air or nitrogen on the measuring result.

14 CarboQC Methods

62 C26IB001EN-B

14 CarboQC Methods

14.1 Available Methods with CarboQC

14.1.1 Standard Methods

The 7 standard methods do not allow to change any parameter at all. It can be

seen from Chapter 8.2 which method is recommended for which beverage

sample. These methods do not provide any means for compensating temperature

effects due to the headspace volume of beverage packages. They are therefore

suitable for determining the true dissolved carbon dioxide content at a given

package temperature.

14.1.2 Customer-Specific Methods

CarboQC provides 17 customer-specific methods. 7 methods, ending with "c",

use solubility coefficients identical to the standard methods, and 10 customer-

specific methods CMxxPROD also allow the entry of the solubility coefficient.

The 7 user-specific methods are named identically to the standard methods with

additional letters "cc" to obtain eight digits altogether (DIETcccc; SPARKLcc and

so on). These 7 methods allow modification of the constants k0 to k7, but these six

methods do not allow access to the solubility coefficient for CO2 in the respective

sample. The solubility coefficients in these user-specific methods are identical tothe ones in the respective standard methods. The coefficients k0 to k7 can be used

to compensate headspace related package temperature effects and to adapt the

measurement results to those based on customer-specific solubility tables or

formulae.

There are also 10 CMxxPROD methods; xx = 01, ..., 10. These 10 customer-

specific methods allow the modification of the constants k0 to k7, but also the

alteration of the solubility coefficient ks of CO2 in the sample.

14.2 Establishing Customer-Specific Formulae

14.2.1 Converting the CO2 Result into a Customer-Specific

Result

In the customer-specific methods the calculated g/L results can be converted for

user-specific CO2 tables or formulae. This conversion can also correct the

temperature-dependent changes of the dissolved CO2 content resulting from the

headspace to liquid volume ratio of the bottles or cans.



14 CarboQC Methods

C26IB001EN-B 63

This equation is used for custom-tailoring a CO2 result from the original CO2

content c as determined by CarboQC.

Ccust is the customer-specific CO2 result. It is the modified carbon dioxide content

that is calculated and displayed when customer-specific coefficients are used.

k0 will always be added to the result c. The factory setting of k0 = 0.

k1 is a multiplication factor. The factory setting of k1 = 1.

k5 is a reference temperature that needs to be keyed in if the result is to be related

to a specific temperature. The factory setting of k5 is zero, which means that k5

equals 0 °C, regardless of the temperature units selected in the menu.

A simple way of applying a reasonable temperature correction for the headspaceinfluence is to use the customer-specific methods in CarboQC, rename them

properly and set k5 equal to the average measuring temperature, and for k2 a

value of 0.003 (typical range: 0.002 … 0.004) to get the temperature

compensation to take effect.

k3 and k4 can be used for better fine tuning of the final customer-specific result.

The factory setting is 0.

Example:

If the result given by CarboQC is 3 g/L and the desired or expected result is 3.3g/L, there are two ways CarboQC can be programmed in order to transfer the

CarboQC result into the customer-specific result:

(1) k0 is set to 0.3

The value ccust will be 0.3 g/L higher than the CarboQC result. This will also affect

the zero determination with deionized water. A k0 of 0.3 will cause an offset as all

results will be 0.3 higher than the determined value: instead of 0 the displayed

result will be 0.3; instead of 2 the displayed result will be 2.3 and so forth.

Therefore setting a positive k0 offset is a reasonable means to adapt the CarboQC

results to readings of previous methods which were offset by a fairly constant aircontent of the samples.

Ccust.......................... Customer-specific CO2 result [g/L]

k0, k1, k2, k3, k4 ........ Customer-specific coefficients

2+ +=



14 CarboQC Methods

64 C26IB001EN-B

(2) k1 is set to 1.1

The CarboQC result will be multiplied by 1.1. Instead of 3 the result will be 3.3 and

instead of 2 the result will be 2.2. If the zero point adjustment works correctly, the

zero reading will be close to zero and multiplication by 1.1 will not affect the zero

reading noticeably. As an example, a factor of approximately 1.1 is often

necessary if the customer-specific solubility table applied is actually a CO2

solubility table for water, but it is applied to 10 °Brix soft drinks.

14.2.2 Converting the CO2 Concentration into a Customer-

Specific Unit

For all customer-specific methods, the measured CO2 concentration can be

converted from g/L into a customer-specific unit.

Proceed as follows:

1. In the menu "methods" , select the desired customer-specific method.

2. Select the menu item "unit" and enter a name for the desired unit (maximum

length of 6 characters).

3. In the menu "methods" , change the coefficient "k1" so that the desired

conversion is applied. E.g. setting k1 = 2, results in multiplying the result by 2.

4. Change to the measuring window and select the changed method using the

<Method> key.

The newly set unit is displayed in the line for the CO2 content. When

measuring, the conversion is carried out according to the entered coefficientand the calculated result is displayed.

5. The factor "fu" is a division factor which divides a customer-specific

polynomial. E.g. using fu = 1.976 leads to converting the measurement result

from g/L into vol.

14.2.3 Using a Customer-Specific Solubility Coefficient

The 10 CMxxPROD methods allow entry of k1 to k7 and, in addition, the solubility

coefficient ks in g/(L * bar) at a temperature of 20 °C. These 10 methods need to

be used when a sample does not match the ranges as given in Chapter 8.2; e.g.

1.61 g/(L * bar) for a 5 ±2 °Brix soft drink.

C26IB001EN-B 65

14.3 Transformation of the Determined Air Content

The following formula serves two purposes:

1. It allows to correct the ppm result with a different slope k6.2. It allows to compensate for the temperature dependent gas distribution in the

beverage container using k5, k7. The term in brackets is set to 1 if k7 0.

This formula is used if the "air ppm" result needs to be corrected or the amount of

gas in the head space needs to be taken into consideration. ctrans is the air content

as a function of head space.

The factory setting for the "slope" k6 is 1.

cair is the air content in ppm as determined by CarboQC.

k5 is the reference temperature and Lb2 is the solubility of air at the determined

measuring temperature T2[K].

Lb(k5) is the solubility of air at the reference temperature k5. This value can betaken from a table.

k7 is the head space to liquid ratio of the beverage container. If k7 0 then the

term in brackets equals 1; if k7 > 0 then the term in brackets is calculated.

Ctrans ........... Air content as a function of head space

k5 ............... Reference temperature [°C]

k6 ............... Slope

k7 ............... Headspace to liquid ratio of can/bottle

cair ............. . Air/nitrogen content in ppm as measured

14.4 Calculation of the Package Pressure at a

Reference Temperature

The 10 CMxxPROD methods CM01PROD to CM10PROD not only allow entry of

coefficients k0 to k7 and ks, but also of the coefficients ka, kb, kc and kd. The

coefficients ka, kb, kc and kd can be modified if the package pressure, determined

at sample temperature, needs to be converted into the package pressure at a

reference temperature.

TIP The value for the pressure at a reference temperature pref can be obtained as

relative pressure if the ambient pressure in [bar] is keyed in. If kd is zero, the

obtained value of pref will correspond to the absolute pressure.

Example: Calculation of the relative reference pressure of sparkling wine at 20°C

(68°F)

1. Select the menu "methods" .

2. Choose any CMxxPROD method.

3. Re-name the method and give it a significant denotation, e.g. SPARKL20.

4. Leave "f u = 1".

5. Leave "k0" to "k4" and "k6" to "k7" unchanged.

6. Select the reference temperature "k5" and change the entry to "+20.0000" .

When setting "k5" , always enter the numerical value of °C, even if the unit Fis selected.

7. Set "ks = 1.51" (ks for SPARKL is 1.51 g/(L*bar)).

pref .............. Package pressure at reference temperature

pt ................ Package pressure as determined by CarboQC

ka ................ Conversion factor for pressure unit

Factory setting = [bar]. If the unit [bar] is desired, set ka = 1.

kb, kc ........... Factor for temperature compensation

Factory setting: +0.00000

Recommendation:

kb = -0.028 (negative sign!) and kc = 0.00075

kd ................ Ambient pressure in [bar]. Factory setting: +0.00000

8. Set "ka" to "kc" as follows:

• ka = 1• kb = -0.028• kc = 0.00075

9. Change the preset value of "kd" and enter the average ambient pressure in

[bar].

Then

pref, 20 = 1 * {ptas determined at t * [1 - 0.028 (t - 20) + 0.00075 * (t - 20)²] - 1}

is the relative package pressure had it been measured at 20 °C (68 °F).

Appendix D: Error Messages

Display Cause Correction

air: "error" Air value out of specification. • Select the proper method for yoursample.

• Rinse the measuring chamber.Repeat the measurement. If the errorpersists, contact your Anton Paarrepresentative.

• Make sure that the CO2 concentration

of the sample is within specifications(Appendix A).

"CO2 - - - - - g/L" CO2 value out of range.

• Bubbles in the measuring cell.

• The measuring chamber is nottightly closed duringmeasurement.

• Make sure that the measuringchamber is free of bubbles.

• Contact your Anton Paarrepresentative.

"air: - - - - - ppm" Air value is not determined, e.g if

"compensation" is set "off" .

Activate the compensation in the menu

"adjustment > compensation" .



Appendix E: Troubleshooting

C26IB001EN-B 73

Appendix E: Troubleshooting

Q The CO2 reading of the water check with deionized water shows >0.03 g/L CO2.

A Sometimes, deionized water contains absorbed CO2 and displays the amountof CO2 absorbed. Either heat up and boil the water and cover it up while cooling

down or do the water check with tap water – but do not forget to rinse the

measuring chamber with deionized water afterwards!

Q The CO2 reading of the first sample after a water check is low.

A If you go from samples containing very low to very high CO2 contents, the first

result for the high CO2 content is slightly lower than the following ones. If only

limited amounts of sample are available, it is a good idea to condition the

instrument by e.g. measuring mineral water after the water check before

measuring the first sample.
