This document describes the site preparation requirements required for a 8355, 8355 S Sulfur Chemiluminescence Detector (SCD) or 8255, 8255 S Nitrogen Chemiluminescence Detector (NCD). For more information, see the GC, GC/MS, and ALS Site Preparation Guide that shipped with the GC. (See the Agilent Technologies GC and GC/MS User Manuals & Tools DVDs.)

Installation Supplies

See “Gas Supplies” on page 12 for the gas types needed for the detector. If any supplies require a new gas cylinder, you must provide the fittings and reducers required to convert a cylinder regulator fitting (for example, 1/4-inch male NPT) to the 1/8-inch female Swagelok fitting needed to connect to the detector. These fittings are not included with the detector. For more information, see the Agilent GC, GC/MS, and ALS Site Preparation Guide that shipped with the GC.

Dimensions and Weight

Select the laboratory bench space before the system arrives. Make sure the area is clean, clear, and level. Pay special attention to the total height requirements. Avoid bench space with overhanging shelves. See Table 1.

In addition, the detector vacuum connections require 25 cm (10 in) minimum of space behind the instrument for the vacuum pump hose and electrical connections.

The vacuum hose connecting the detector to the foreline pump is 2.1 m (7 ft) long. The vacuum pump power cord is 2 m (6 ft 6 in) long. If your bench abuts a wall, drill a 3.8 cm (1.5 in) diameter hole through the rear of the bench for the vacuum hose.

A single XCD installs to the right of the GC. A second XCD installs to the left of the GC. Allow for at least 5 cm (2 in) space between the side of the GC and the detector to allow for proper GC ventilation.

Power Consumption

Table 2 lists site power requirements.

• Power consumption and requirements depend on the country to which the unit ships.

• The voltage requirements for your detector are printed near the power cord attachment.

• The electrical outlet for the unit should have a dedicated ground.

Although your detector should arrive with the power cord appropriate for operation in your country, compare the voltage option you ordered against the power cords listed in Table 3. If the voltage option and cable you ordered is not suitable for your installation, contact Agilent Technologies.

To protect users, the metal instrument panels and cabinet are grounded through the three-conductor power line cord in accordance with country and regional power requirements.

The three-conductor power line cord, when plugged into a properly grounded receptacle, grounds the instrument and minimizes shock hazard. A properly grounded receptacle is one

WARNING Do not use extension cords with Agilent instruments. Extension cords normally are not rated to carry enough power and can be a safety hazard.

CAUTION A proper earth ground is required for operation. Any interruption of the grounding conductor could cause a shock that could result in personal injury.

Exhaust Venting

During normal operation of the detector the carrier gas and sample are combusted in the burner assembly and then vented through the vacuum pump. The detector also includes an ozone-destroying chemical trap on the vacuum pump intake. If any residual components are still toxic or noxious, vent these exhausts to a fume hood or other exhaust vent system.

Note that an exhaust vent system should not be part of the building environmental control system. A building environmental control system recirculates air within the lab.

Exhaust venting must comply with all local environmental and safety codes. Contact your Environmental Health & Safety (EHS) specialist.

Environmental Conditions

Operating the detector within the recommended ranges optimizes instrument performance and lifetime. Performance can be affected by sources of heat and cold from heating, air conditioning systems, or drafts. See Table 4. The conditions assume a noncondensing, noncorrosive atmosphere. The instrument meets the following International Electrotechnical Commission (IEC) classifications: Equipment Class I, Laboratory Equipment, Overvoltage Category II, and Pollution Degree 2, indoor use.

Gas Purity

Agilent recommends that carrier and detector gases be 99.9995 % pure. See Table 5. Air needs to be zero grade or better. Agilent also recommends using high quality traps to remove hydrocarbons, water, and oxygen.

Moisture in the ozonizer gas can damage the detector. Agilent strongly recommends the use of a moisture trap for the ozonizer gas supply.

Hydrogen 99.9995 % SFC grade

Air (oxidizer for SCD) 99.9995 %

Oxygen (oxidizer for NCD, ozonizer for all) 99.9995 %

Gas Supplies

General requirementsSupply detector gases using tanks, an internal distribution system, or gas generators. If used, tanks require two-stage pressure regulators with packless, stainless steel diaphragms. The detector requires 1/8-inch Swagelok connections to its gas supply fittings.

Table 6 lists available Agilent two-stage tank regulators. All Agilent regulators are supplied with the 1/8-inch Swagelok female connector.

1/8-inch male

NOTE Plumb the gas supply tubing/regulators so that one 1/8-inch Swagelok female connector is available for each gas needed at the detector.

Table 7 lists minimum and maximum delivery pressures for the detector, measured at the bulkhead fittings on the back of the detector.

The minimum supply pressure for the detector modules is 138 kPa (20 psi) greater than the pressure used in your method. For example, if you need a pressure of 138 kPa (20 psi) for the method, the supply pressure must be at least 276 kPa (40 psi).
