Environmental Conditions
Operating your instrument within the recommended temperature ranges ensures optimum instrument
performance and lifetime.
Performance can be affected by sources of heat & cold e.g. direct sunlight, heating/cooling from air
conditioning outlets, drafts and/or vibrations.
The site’s ambient temperature conditions must be stable for optimum performance.
For storage or shipping, the allowable temperature range is -40 to 70 C and the allowable humidity
range is 5-95%, non-condensing. After exposing the GC to extremes of temperature or humidity,
allow 2 hours for it to return to the recommended ranges.

Your facilities manager may wish to know the amount of heat that the system generates in order to
establish its contribution to the overall room ventilation requirements.
The following table may help you calculate the additional BTU’s of heat dissipation from this new
equipment. Maximums represent the heat given off when heated zones are set for maximum
temperatures.
Refer to the "Heat Dissipation" section of the " Agilent 7890 Gas Chromatograph Site Preparation Guide " for
more detail.

Venting 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 hydrogen carrier gas with either a micro Electron Capture (uECD) or Thermal Conductivity (TCD)
Detector the GC will vent uncombusted hydrogen from the detector exit. In addition, if a Split/Splitless or
Multimode Inlet is used, hydrogen will dissipate from both the inlet split and septum purge vents. In both
cases you must either safely vent the exhaust gas or operate the GC inside a fume hood.
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.
Below is a picture that shows the back view of a 7890 GC with the micro Electron Capture Detector vent tube
exiting the back of the instrument.

Notes
The number and type of electrical outlets depends on the size and complexity of your system. For
example, in addition to the dedicated outlet for the GC, a system with a computer, monitor, printer, and
HUB/Switch requires 4 additional outlets on a separate circuit.
The outlet for the GC must be dedicated to the GC with a dedicated ground.
The GC will have a label next to the power cord connector that describes the line voltage requirements.
Option 003 is for any Country with standard 120/240 VAC to accommodate 208 VAC Power.
Power line conditioners that contribute any power line distortion should not be used with the Agilent
7890 GC.
Refer to the "Power Consumption" section of the "Agilent GC, GC/MS, and ALS Site Preparation Guide"
for more detail.
It is important to measure the line voltage at the receptacle for the GC to insure compatibility with
the power configuration of the GC.

If planning to use hydrogen carrier gas, note that special considerations apply due to hydrogen’s flammability and
chromatographic properties. Refer to the to the "Gas Supplies/Requirements for Hydrogen as a Carrier Gas" section
in the "Agilent GC, GC/MS and ALS Site Preparation Guide" for more detail.
Hydrogen Safety
When using hydrogen as the carrier gas or fuel gas, be aware that hydrogen gas can flow into the GC oven and
create an explosion hazard. Therefore, be sure that the Hydrogen gas supply is turned off until all connections are
made and ensure the inlet and detector column fittings are either connected to a column or capped at all times
when hydrogen gas is supplied to the instrument.
In any application using hydrogen, leak test all connections, lines, and valves before operating the instrument.
Agilent highly recommends the G3388B Leak Detector or equivalent to safely check for leaks.
Supply tubing for Hydrogen Gas
Agilent recommends using NEW, chromatographic quality copper or stainless steel tubing and fittings when
using hydrogen.
Do not re-use old tubing when installing or switching to hydrogen carrier gas. Hydrogen gas tends to remove
contaminants left on old tubing by previous gases (by helium, for example).
These contaminants can appear in detector output as high background noise or hydrocarbon
contamination for several weeks.
Do not use old copper tubing with hydrogen gas. Old copper tubing can become brittle and create a safety
hazard.
Hydrogen Gas Supplies
Hydrogen can be supplied from a gas generator or from a cylinder.
Agilent recommends use of a high-quality hydrogen gas generator. A high-quality generator can consistently
produce purity > 99.9999%, and the generator can include built-in safety features such as limited flow rates,
and auto-shutdown.
If using a hydrogen gas cylinder, Agilent recommends use of Gas Clean Filters to purify the gas. Consider
additional safety equipment as recommended by your company safety personnel.
