10BVenting the Oven - Oven Heat Deflector Option 306 or Part Number G1530-80650

Below is a picture that shows the back view of an installed 7890 GC - with the Oven Heat Deflector

installed. The exhaust duct is 10 cm (4 inches) in diameter and adds 14 cm (5.5 inches) to the back of the

GC.

The connecting duct should provide unrestricted flow for the oven air and be as short and straight as

possible.

With the exhaust deflector installed the exhaust is about 65 CFM (ft3/min /1.840 m3/min). Without the

deflector, the exhaust rate is about 99 CFM (ft3/min /2.8 m3/min).

Refer to the "Exhaust Venting" section of the "Agilent GC, GC/MS, and ALS Site Preparation Guide" for

more detail.

Venting the uECD, TCD or Split-Splitless Inlet Vent gas flows to a Fume Hood or venting

manifold

If using a micro Electron Capture Detector, or if using hydrogen carrier gas that will be uncombusted,

you must either safely vent the exhaust gas, or operate the GC inside a fume hood.

For example, if using hydrogen carrier gas with a thermal conductivity detector (TCD) the GC would

vent uncombusted hydrogen from the detector and from the inlet split and septum purge vents.

The uECD exhaust vents through a stainless steel tube, connected to a length of large I.D. tubing that

exits the back panel. This should be routed to a fume hood or appropriate venting system. Agilent

Technologies recommends a vent line internal diameter of 6 mm (1/4-inch) or greater. With a line of this

diameter, the length is not critical. Make sure that the venting system does not put a direct negative

pressure on the vent tube from the GC.

tube exiting the back of the instrument.

27BGas Selection

12BSpecial Notes

1. Refer to the "Gas and Reagent Selection" section in the "Agilent GC, GC/MS and ALS Site

Preparation Guide" for more detail.

2. Agilent recommends a carrier and detector gas purity of 99.9995% or better. Air for flame

detectors should be zero grade. Agilent also recommends using traps to remove hydrocarbons,

water, and oxygen.

3. When used with capillary columns, GC detectors require a separate makeup gas for optimum

sensitivity. This table lists gas recommendations for capillary columns and the preferred makeup

gas types.

4. The inlet electronic pressure control (EPC) modules are calibrated for up to 4 carrier gases:

Split/Splitless capillary (SS), Purged packed (PP), Programmable temperature vaporization

(PTV), Multi-Mode (MM), and cool on-column (COC) are calibrated for Helium, Hydrogen,

Nitrogen, and Argon methane 5%.

Volatiles inlet VI is calibrated for only Helium and Hydrogen.

5. For GC/MS requirements, refer to the "GC/MS Gas and Reagent Requirements" section in the

33BGas Plumbing and Supplies

Plumbing Considerations

1. Refer to the "Gas Plumbing" section in the "Agilent GC, GC/MS and ALS Site Preparation Guide"

for more detail.

2. Gases are supplied by tanks, internal distribution system, or gas generators. Tank supplies

require two stage, pressure regulation. To connect tubing to the supply, it must have one 1/8-inch

Swagelokfemale connector for each gas. Make sure that your regulator has the appropriate

sized adapter to end with a 1/8-inch Swagelokfemale connector.

3. If your order did NOT include parts to connect the gas supply to your 7890 GC, you must supply

pre-cleaned, 1/8-inch copper tubing and a variety of 1/8-inch Swagelokfittings to connect the

gas supply(s). Refer to the "GC Installation Kits" and "GC Plumbing" sections of this checklist for

Part Numbers.

4. Never use liquid thread sealer to connect fittings. Never use chlorinated solvents to clean

tubing or fittings.

5. Agilent also recommends using traps to remove water, hydrocarbons, and oxygen or a

combination trap such as the "Gas Clean" Filter System that removes all three.

Special Notes

1. Shutoff Valves are recommended at both front and back Inlet Carrier Connections

2. FID, FPD and NPD need dedicated detector air supply

3. For Gas supply runs longer than 15 feet, use 1/4 inch tubing to prevent pressure drop

4. Do not reuse old copper tubing which can become brittle and break

Gas Clean Filter Configurations

Refer to the "Gas Plumbing/Filters and Traps" section of the "Agilent GC, GC/MS, and ALS Site

Preparation Guide" for more detail. Another good resource is the "Agilent Gas Clean Filter System User
