Site Preparation Checklist
Site Preparation Checklist
For typical system requirements for system installation, see the diagrams on page 8 through
page 9.
Use the following checklist to ensure that the site is properly prepared for GC system
installation.
1 Ensure that the appropriate installation hardware has been acquired.
See “Installation Kits” on page 14.
2 Ensure that the location in which the GC system is being installed meets the
requirements for environmental conditions. See “Environmental Conditions” on
page 24. Also see “Heat Dissipation” on page 25.
3 Prepare bench space for the GC system. Ensure that the bench has the size and
weight capacity to accommodate the GC and associated components. See “Bench
Preparation” on page 7. Also see “Dimensions and Weight” on page 18.
4 Ensure that system components are oriented so that they can be connected
properly. See “Maximum Length of Cables and Hoses” on page 10.
5 If the system being installed includes an MSD, ensure that the bench allows for
proper installation and connection of the foreline pump. See “Foreline Pump
Requirements for Systems Including an MSD” on page 20.
6 Ensure that appropriate venting is provided for the GC system. See “Exhaust
Venting” on page 28.
7 Ensure that a dedicated power circuit is available for each device in the system.
See “Power Requirements” on page 32.
8 Ensure that appropriate gas and reagent supplies are provided for the GC system.
See “Gas and Reagent Selection” on page 40.
9 Ensure that appropriate gas plumbing is provided for the GC system. See “Gas
Plumbing” on page 49.
10 If the GC system being installed includes a data system, ensure that the PC meets
the requirements necessary to properly support the GC system. For more
information, see the site prep guide for your data system.
11 If the GC being installed is to be connected to a site LAN, ensure that the appropriate
cabling is available. See “Site LAN Network” on page 56.

Bench Preparation
Bench Preparation
When planning a bench layout:
• Consider component dimensions, weights, and space requirements. See “Dimensions and
Weight” on page 18.
• Consider the lengths of cables and hoses for connection of components. See “Maximum
Length of Cables and Hoses” on page 10.
• For systems that include an MS, consider foreline pump requirements. See “Foreline
Pump Requirements for Systems Including an MSD” on page 20.
• Allow space for operational access.
• Note that the 7200 Q-TOF requires 48 cm (1.6 ft) of space in front to allow for the RIS
probe extraction tool handle when installed.
• Note that some repairs to the GC/MS, or to the GC itself, will require access to the back of
the instrument(s).
Examples are provided here for systems including a GC with an ALS, computer and printer.
Most examples also include an MS.
See several example layouts below.

5 Exhaust Venting
WARNING
Exhaust Venting
Exhaust Venting
During normal operation, the GC exhausts hot oven air. Depending on the installed inlet and
detector types, the GC can also exhaust (or vent) uncombusted carrier gas and sample. Proper
venting of these exhausts is required for operation and safety.
Venting hot air
Do not place temperature-sensitive items (for example, gas cylinders, chemicals, regulators,
and plastic tubing) in the path of the heated exhaust. These items will be damaged and
plastic tubing will melt. Be careful when working behind the instrument during cool-down
cycles to avoid burns from the hot exhaust.
1 Hot air (up to 450 °C) from the oven exits through a vent in the rear of the instrument. Allow
at least 25 cm (10-inch) clearance behind the instrument, or 30 cm (12-inch) behind a
Q-TOF GC/MS to dissipate this hot air. See Figure 4.
Figure 4. Exhaust outlet.
2 For most applications, an optional oven exhaust deflector is available. The exhaust
deflector allows for less bench depth than a GC without the exhaust deflector installed.
• The GC exhaust deflector is included if GC option 306 is ordered. The exhaust deflector
requires 14 cm (5.5 inches) behind the instrument. For GCs with the exhaust deflector
option installed, the exhaust rate is about 65 ft
deflector, the exhaust rate is about 99 ft

Venting other gases
During normal operation of the GC with many detector and inlet types, some of the carrier gas
and sample vents outside the instrument through the split vent, septum purge vent, and
detector exhaust. If any sample components are toxic or noxious, or if hydrogen is used as the
carrier gas or detector fuel gas, these exhausts must be vented to a fume hood.
Exhaust venting must comply with all local environmental and safety codes. Contact your
Environmental Health & Safety (EHS) specialist.
1 Place the GC in the hood or attach a large diameter venting tube to the relevant outlet for
proper ventilation. See “Exhaust vent fittings” on page 30.
2 To further prevent contamination from noxious gases, attach a chemical trap to the
vent(s).
3 If using an ECD, always connect the ECD exhaust vent to a fume hood or vent it to the
outside. See the latest revision of 10 CFR Part 20 (including Appendix B), or the applicable
state regulation. For countries other than the United States, consult with the appropriate
agency for equivalent requirements. Agilent 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.

Exhaust vent fittings
The various inlet and detector vents terminate in the following fittings:
• TCD, ECD: The detector exhaust terminates in a 1/8-inch od tube.
• SSL: The split vent terminates in a 1/8-inch Swagelok female fitting.
• All inlets: The septum purge vent terminates in 1/8-inch od tubing.

Power Requirements
Power Requirements
Power consumption and requirements depend on the country to which the unit ships.
The number and type of electrical outlets depend on the size and complexity of the system.
To protect users, the metal instrument panels and cabinet are grounded through the
three-conductor power line cord in accordance with International Electrotechnical
Commission (IEC) requirements.
A proper earth ground is required for GC operations. Any interruption of the grounding
conductor or disconnection of the power cord could cause a shock that could result in
personal injury.
Be sure to verify proper receptacle grounding.
Do not use extension cords with Agilent instruments. Extension cords normally are not rated
to carry enough power and can be a safety hazard.
The length of the power cord is 2 meters (6.6 feet).
Do not use power line conditioners with Agilent instruments. Doing so may cause damage to
the equipment.
1 Ensure that each instrument in your GC system can be connected to a dedicated circuit
with an isolated ground. (Note that ALS instruments receive their power from the GC.)
2 Power requirements are printed near the power cord attachment on the rear panel of each
instrument. Although your GC should arrive ready for operation in your country, compare
its power requirements with those listed in Ta ble 10. If the voltage option you ordered is
not suitable for your installation, contact Agilent Technologies.

USA fast heating oven, 240 V
The 240 V fast heating oven requires 240 V/15 A power. Do not use 208 V power. Lower
voltage causes slow oven ramps and prevents proper temperature control. The power cord
supplied with your GC is rated for 250 V/15 A, and is a two-pole, three-wire cord with grounding
(type L6-15R/L6-15P).
Canadian installation
When installing a GC in Canada, make sure your GC power supply circuit meets the following
additional requirements:
• The circuit breaker for the branch circuit, which is dedicated to the instrument, is rated for
continuous operation.
• The service box branch circuit is marked as a “Dedicated Circuit.”

7 Gas Selection and Plumbing
WARNING
NOTE
Gas and Reagent Selection
Gas and Reagent Selection
Table 12 lists gases usable with Agilent GCs and capillary columns. When used with capillary
columns, GC detectors require a separate makeup gas for optimum sensitivity. The MS and
MSD use GC carrier gas.
If you are using any MS system, use of hydrogen as the carrier gas may require hardware
modifications for the best performance. Contact your Agilent service representative. Hydrogen
is not supported as a carrier gas with the 7200/7250 GC/Q-TOF system.
When using hydrogen (H2) as the carrier gas or fuel gas, be aware that hydrogen gas can flow
into the GC and create an explosion hazard. Therefore, be sure that the 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.
Hydrogen is flammable. Leaks, when confined in an enclosed space, may create a fire or
explosion hazard. In any application using hydrogen, periodically leak test all connections,
lines, and valves before operating the instrument or after maintenance. Always turn off the
hydrogen supply at its source before working on the instrument.
Please refer to the Hydrogen Safety Guide shipped with your instrument.
Hydrogen use is specifically prohibited with the 7200 or 7250 GC/Q-TOF system.
Nitrogen and Argon/Methane are generally not suitable for GC/MS carrier gas.

MS and MSD systems purchased with a Self-Cleaning Ion Source also require a source of
hydrogen gas in addition to helium carrier gas. This source can be shared but must meet
carrier gas purity requirements.
Hydrogen Carrier Gas
Refer to the Agilent 8860 GC Safety Manual for important safety information about hydrogen
gas.
If hydrogen is being used as a carrier gas, or for the JetClean ion source system, special
considerations apply due to hydrogen’s flammability and chromatographic properties.
• Agilent highly recommends the G3388B Leak Detector to safely check for leaks.
• Hydrogen carrier gas requires special considerations for supply tubing. See “Gas
Plumbing” on page 49.
• In addition to the supply pressure requirements listed in “Gas Supplies” on page 43, Agilent
also recommends users of hydrogen gas consider gas source and purification needs. See
the additional recommendations in “Requirements for hydrogen as a carrier gas or for
use in JetClean systems” on page 45.
• When using hydrogen carrier gas with a ECD, TCD, or any other detector that vents
uncombusted gases, plan to vent the detector output to a fume hood or similar location.
Uncombusted hydrogen can present a safety hazard. See “Exhaust Venting” on page 28.
• When using hydrogen carrier gas, also plan to safely vent inlet split vent flows and purge
vent flows. See “Exhaust Venting” on page 28.
Gas and Reagent Purity
Agilent recommends that carrier and detector gases be 99.9995% pure. See Table 1 5 . Air
needs to be zero grade or better. Agilent also recommends using high quality traps to remove
hydrocarbons, water, and oxygen.

Requirements for hydrogen as a carrier gas or for use in JetClean systems
Not all systems can use hydrogen as a carrier gas. See Gas Selection.
Hydrogen can be supplied from a 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 storage, limited flow rates, and auto-shutdown. Select a hydrogen
generator that provides low (good) specifications for water and oxygen content.
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.

Gas Plumbing
All compressed gas cylinders should be securely fastened to an immovable structure or
permanent wall. Compressed gases should be stored and handled in accordance with the
relevant safety codes.
Gas cylinders should not be located in the path of heated oven exhaust.
To avoid possible eye injury, wear eye protection when using compressed gas.
Site Preparation Guide 49
Figure 7. Recommended filters and plumbing configuration from a carrier gas cylinder
• If you have not requested option 305 (pre-plumbed tubing), you must supply pre-cleaned,
1/8-inch copper tubing and a variety of 1/8-inch Swagelok fittings to connect the GC to
inlet and detector gas supplies. See the Installation Kits for recommended parts.
• Agilent strongly recommends two-stage regulators to eliminate pressure surges.
High-quality, stainless-steel diaphragm-type regulators are especially recommended.
• On/off valves mounted on the outlet fitting of the two-stage regulator are not essential but
are very useful. Be sure the valves have stainless-steel, packless diaphragms.
• Agilent strongly recommends installation of shut-off valves at each GC inlet supply fitting
to allow the GC to be isolated for maintenance and troubleshooting. Order part number
0100-2144. (Note that some optional installation kits include one shut-off valve. See
“Installation Kits” on page 14 for more information.)
• If you purchased automated valving, the valve actuation requires a separate pressurized,
dry air supply at 380 kPa (55 psig). This air supply must end in a male fitting compatible
with a 1/4-inch id plastic tube at the GC.
7 Gas Selection and Plumbing
CAUTION
CAUTION
Supply tubing for most carrier and detector gases
• FID, FPD, and NPD detectors require a dedicated air supply. Operation may be affected by
pressure pulses in air lines shared with other devices.
• Flow- and pressure-controlling devices require at least
10 psi (138 kPa) pressure differential across them to operate properly. Set source
pressures and capacities high enough to ensure this.
• Situate auxiliary pressure regulators close to the GC inlet fittings. This ensures that the
supply pressure is measured at the instrument (rather than at the source); pressure at the
source may be different if the gas supply lines are long or narrow.
• Never use liquid thread sealer to connect fittings.
• Never use chlorinated solvents to clean tubing or fittings.
See “Installation Kits” on page 14 for more information.
Supply tubing for most carrier and detector gases
Use only preconditioned copper tubing (part number 5180-4196) to supply gases to the
instrument. Do not use ordinary copper tubing—it contains oils and contaminants.
Do not use methylene chloride or other halogenated solvent to clean tubing that will be used
with an electron capture detector. They will cause elevated baselines and detector noise until
they are completely flushed out of the system.
Do not use plastic tubing for suppling detector and inlet gases to the GC. It is permeable to
oxygen and other contaminants that can damage columns and detectors.
Plastic tubing can melt if near hot exhaust or components.
The tubing diameter depends on the distance between the supply gas and the GC and the total
flow rate for the particular gas. Tubing of 1/8-in diameter is adequate when the supply line is
less than 15 feet (4.6 m) long.
Use larger diameter tubing (1/4-inch) for distances greater then 15 feet (4.6 m) or when
multiple instruments are connected to the same source. Use larger diameter tubing if high
demand is anticipated (for example, air for an FID).
Be generous when cutting tubing for local supply lines—a coil of flexible tubing between the
supply and the instrument lets you move the GC without moving the gas supply. Take this
extra length into account when choosing the tubing diameter.
Supply tubing for hydrogen gas
Agilent recommends using new chromatographic quality stainless steel tubing and fittings
when using hydrogen.
• Do not re-use old tubing when installing or switching to hydrogen supply lines for carrier
gas or the JetClean ion source system. Hydrogen gas tends to remove contaminants left
on old tubing by previous gases (by helium, for example). These contaminants can appear
in output as high background noise or hydrocarbon contamination for several weeks.
• Especially do not use old copper tubing, which can become brittle.

Two-stage pressure regulators
Do not use old copper tubing with hydrogen gas. Old copper tubing can become brittle and
create a safety hazard.
Two-stage pressure regulators
To eliminate pressure surges, use a two-stage regulator with each gas tank. Stainless steel,
diaphragm-type regulators are recommended.
The type of regulator you use depends on the gas type and supplier. The Agilent catalog for
consumables and supplies contains information to help you identify the correct regulator, as
determined by the Compressed Gas Association (CGA). Agilent Technologies offers
pressure-regulator kits that contain all the materials needed to install regulators properly.
Pressure regulator-gas supply tubing connections
Use PTFE tape to seal the pipe-thread connection between the pressure regulator outlet and
Site Preparation Guide 51
the fitting to which you connect the gas tubing. Instrument grade PTFE tape (part number
0460-1266), from which volatiles have been removed, is recommended for all fittings. Do not
use pipe dope to seal the threads; it contains volatile materials that will contaminate the
tubing.
Pressure regulators typically end in fittings that must be adapted to the correct style or size.

Filters and traps
Using chromatographic-grade gases ensures that the gas in your system is pure. However, for
optimum sensitivity, install high-quality filters or traps to remove traces of water or other
contaminants. After installing a filter, check the gas supply lines for leaks.
Agilent recommends the Gas Clean Filter system. The Gas Clean Filter system delivers high
purity gases to your analytical instruments, reducing the risk of column damage, sensitivity
loss, and instrument downtime. The filters are designed for use with the GC, GC/MS, ICP-OES,
ICP-MS, LC/MS, and any other analysis instrument using carrier gas. Six filters are available,
including CO2, oxygen, moisture, and organics trap (charcoal).
Filter types
Each Gas Clean Filter type is designed to filter out a specific impurity that may exist in the gas
supply. The following filter types are available:
•Oxygen - Prevents oxidation of the GC column, septum, liner, and glass wool.
•Moisture - Delivers fast stabilization times for increased GC productivity, and prevents
hydrolization damage to the stationary phase, column, liner, glass wool, or septum in the
GC.
• Process Moisture - Prevents oxidation of GC components and is safe to use with acetylene
in process GC applications.
•Charcoal - Removes organic compounds and ensures correct performance of FID
detectors in the GC.
•GC/MS - Delivers fast stabilization times for increased GC productivity, removes oxygen,
moisture, and hydrocarbons from the carrier gas for MS applications, and provides
ultimate GC column protection.
Table 26 lists the most common Gas Clean Filter system kits. See the Agilent online store or
contact your local Agilent sales representative for additional filters, parts, and accessories
applicable to your instrument configuration.

Site LAN Network
Agilent Technologies is not responsible for connecting to or establishing communication
with your site LAN network. The Agilent representative will test the system’s ability to
communicate on a mini-hub or LAN switch only.
If you intend to connect your system to your site’s LAN network, you must have an additional
shielded twisted pair network cable (8121-0940).
The IP addresses assigned to the instrument(s) must be fixed (permanently assigned)
addresses. If you intend to connect your system to your site’s network, each piece of
equipment must have a unique, fixed (static) IP address assigned to it.
For a Single Quad GC/MS system, Agilent recommends, sells, and supports the use of a PC
with one (1) network interface card (NIC) and a network switch to isolate the GC/MS system
from the site LAN. The network switch supplied with Agilent systems prevents
instrument-to-PC network traffic from entering the site LAN and keeps site LAN network
traffic from interfering with instrument-to-PC communications. Agilent develops and tests all
Single Quad GC/MS hardware and software using the single NIC configuration and has no
known network configuration issues. Alternate network configurations can be configured
and managed by the end user at their own risk and expense.
For Triple Quad and 7200 Q-TOF GC/MS systems, Agilent recommends, sells, and supports
the use of a PC with two network interface cards (NIC) to provide both a site LAN connection
and an isolated GC/MS system connection. Agilent develops and tests all Triple Quad and
Q-TOF GC/MS hardware and software using the dual NIC configuration, and has no known
network configuration issues. Alternate network configurations can be configured and
managed by the end user at their own risk and expense.
For the 7250 Q-TOF GC/MS systems, Agilent recommends, sells, and supports the use of a
PC with three network interface cards (NIC) to provide a site LAN connection, MS only
connection, and an isolated GC/MS system connection. Agilent develops and tests Q-TOF
GC/MS hardware and software using the triple NIC configuration, and has no known network
configuration issues. Alternate network configurations can be configured and managed by
the end user at their own risk and expense.
