NOTEAttentionisdrawnto the need to designequipmentforhandling carbon dioxide such that it is either capable ofwithstandingthepressuresinvolvedor protectedfromthem.8.2 Sampling EquipmentRigid metal connections or flexible reinforced nylonhose should be used throughout the samplingequipment and shall be kept as short as possible. Allcomponents shall have a design pressure of not lessthan 137 bar.8.3 Procedure8.3.1 GeneralTwo methods of sampling are specified as follows:

a) Direct sampling, in which the sample ispassed to an evaporator and then directly tothe analytical apparatus; andb) Sampling in cylinders, in which case thesample is transferred in a cylinder to alaboratory.

Other methods may be used provided that they areshown to give equally representative samples onanalysis (see Annexes A to C).8.3.2 Direct SamplingConnect the sampling valve by means of suitableconnections (see 8.2) to an evaporating device andthen via a T-piece (the free leg of which is connectedto the dip-tube of a Drechsel bottle containing 50 mmof mercury covered by a layer of water on the carbondioxide side) to the analytical apparatus. Thoroughly

flush the connections, valves and the evaporatingdevice with carbon dioxide before starting to take thesample.8.3.3 Sampling in CylindersUse a cylinder of water capacity 1.4 kg or 2.0 kg,complying with the requirements of IS 7285 and witha valve at each end.An internal copper dip-tube of diameter at least 5 mmand of length equal to one-third of the length of thecylinder shall be brazed to the base of one valve, whichshall be clearly identified. The cylinder shall be coatedinternally with tin [containing 1 percent (m/m) of lead]applied by hot dipping the cylinder after the walls havebeen descaled.First clean the sampling cylinder by removing bothvalves and washing the inside of the cylinder withcarbon tetrachloride. Purge with a current of dryfiltered air. Wash with methanol and repeat thepurging. Degrease the valves using carbontetrachloride, then refit them. The methanol andcarbon tetrachloride used shall comply with therequirements specified in B-2.Support the cylinder vertically with its dip-tube valveuppermost. Before taking the sample, thoroughly flushthe cylinder with a small quantity of liquid carbondioxide, first through the top valve and then throughthe bottom valve. Repeat this flushing procedure, andleave the cylinder connected to the liquid carbondioxide source via its lower valve. Then, with the uppervalve closed, open the lower valve to admit liquidcarbon dioxide to the cylinder. Partly open the upper(dip-tube) valve and continue filling until carbondioxide snow is discharged from this valve. Close bothvalves. Open the top valve several times for briefintervals until only carbon dioxide gas is dischargedfrom it. The free end of the dip-tube inside the cylinderwill then be just above the liquid carbon dioxide levelin the cylinder.Samples shall be analyzed as soon as reasonablypracticable after collection. To withdraw the samplefor analysis, support the sampling cylinder verticallywith the dip-tube valve at the top. Connect the bottomvalve of the sampling cylinder (liquid carbon dioxide)to an evaporating device and then via a T-piece, thefree leg of which is connected to a tube as describedin 8.3.2 to the analytical apparatus, Thoroughly flushthe connections, valves and the evaporating devicewith carbon dioxide before starting the anal ysis.When sampling for the determination of water content,the connections to be above the dew-point to preventcondensation during purging.

The tubesshall be filled with the desiccant (A-2.5) which shallbe held in position by small pads of cotton wool.

A-2.2 Flow MeterFloat type, suitable for measuring a carbon dioxideflow of 200 ml/min to 2000 ml/min.A-2.3 Gas MeterCalibrated for 1 or 2.5 litres per revolution.A-2.4 Test SievesOf aperture sizes 425pm and 600 m, complying withthe requirements of IS 460 (Part 1).A-2.5 DesiccantSift powdered glass or clean, dry, washed sand andretain the portion that passes through a test sieveof aperture size 600 pm but is retained on a testsieve of aperture size 425 pmIn general, follow the applicable recommendations andrequirements of IS 460 (Part 1) and IS 460 (Part 2).Quickly transfer to a stoppered container (a largeweighing bottle or small stoppered jar is suitable) avolume of fresh phosphorus pentoxide and add abouthalf as much by volume of the prepared powdered glassor sand. Vigorously shake the container to mix thecomponents and fill the U-tubes (A-2.1) as quickly aspossible with the mixture.lf it is prepared in this way, it should be easy to fill thetube with the desiccant. If it is not easy, it is probablethat the phosphorus pentoxide was moist beforeaddition of the powdered glass or sand.

Prepare the desiccant in small quantities, as required.A-3 SAMPLINGTake the sample in a cylinder by the method describedin 8.3.3. About 120 g of carbon dioxide is requiredfor each determination.A-4 DETERMINATIONAfter the evaporating device, connect the exit side ofthe T-piece to the absorption tubes (A-2.1), the flowmeter (A-2.2), and the gas meter (A-2.3) in series, inthat order.Carefully open the regulating valve and absorptiontube taps and allow the gas to flow at a rate of about500 ml/min for 10 rein; the carbon dioxide displacesthe air in the absorption tubes. Close all taps,disconnect the absorption tubes and wipe the tubessurfaces with a dry, soft cloth. Place the absorptiontubes in the balance case, leave for 20 rein, then weighthem to the nearest 0.5 mg.Reconnect the absorption tubes. Note the reading ofthe gas meter then allow the gas to pass at a steadyrate of 500 ml/min to 1000 ml/min for 1 h.Close the taps and reducing valve.

of the evaporating device and then to the Drechselbottle, the two bubblers, the flow meter and the gasmeter in series, in that order, using short rubberconnections.No carbon dioxide shall be allowed to pass to theatmosphere through the outlet of the T-piece.Weigh the cylinder, totally expand the contents of thecylinder through the absorption train at a flow rate ofabout 1000 ml/min, and read the volume of gas passed(this serves as a check on the amount of carbon dioxideused for the test).

NOTES1Someevaporationofthecarbon tetrachloride will take place.Ifthk is excessive,stop the flowof gas and refill the absorptionbottles,notingthevolumeofcarbontetrachloride.2 Inviewofthe toxicnatureofcarbontetrachloride,theeffluentgasfromthisdeterminationshouldbedischargedto theoutsideair.

Reweigh the sampling cylinder, taking care to use thesame valve fittings as at the first weighing. Removethe valve not attached to the dip-tube and wash theinside of the cylinder with 25 ml of the carbontetrachloride. Wash the interior of the evaporatingdevice and valves with carbon tetrachloride andcombine this solution with the cylinder washings andthe contents of the bubblers. Make up the combinedsolutions to some suitable, definite volume.B-5.2 Preparation of Blank Test SolutionEvaporate a volume of carbon tetrachloride, equal tothe total volume (including any additions) of carbontetrachloride used in the absorption train pluswashings, to the volume of the combined solution(see B-5.1) and subsequently treat it in the same wayas the test solution.B-5.3 Spectrometric MeasurementsFollowing the manufacturers instructions for theoperation of the instrument, determine the absorbanceof the test solution and of the blank test solution atthe wavelength of maximum absorption (approxi~mately 3460 rim). From the calibration graph (B-5.4),deduce the masses of oil corresponding to the measuredabsorbance.B-5.4 Preparation of the Calibration GraphPrepare suitable dilutions of the standard solution (B-2.2)to cover the range within which the mass of oil in thesample is expected to be found. Measure the absorbanceof each of these solutions as described in B-5.3. Preparea calibration graph by plotting the masses of oil againstthe corresponding absorbance.
