This guide outlines the site requirements for GC, GC/MS, and automatic liquid sampler (ALS)
installation. Site requirements include the necessary space, electrical supplies, gas supplies,
operating supplies and consumables required to successfully install the GC and related
instruments and systems.
The site must meet the requirements specified in this guide before beginning installation.
Refer to the Agilent Web site at www.agilent.com for the most up-to-date listing of GC, GC/MS,
and ALS supplies and consumables.

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.
1Ensure that the appropriate installation hardware has been acquired.
See “Installation Kits” on page 14.
2Ensure 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.
3Prepare 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.
4Ensure that system components are oriented so that they can be connected
properly. See “Maximum Length of Cables and Hoses” on page 10.
5If 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.
6Ensure that appropriate venting is provided for the GC system. See “Exhaust
Venting” on page 28.
7Ensure that a dedicated power circuit is available for each device in the system.
See “Power Requirements” on page 32.
8Ensure that appropriate gas and reagent supplies are provided for the GC system.
See “Gas and Reagent Selection” on page 40.
9Ensure 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.

The supporting surface for the 7200/7250 Q-TOF GC/MS system should be kept relatively
vibration free. Do not put the rough pump on your laboratory bench with the 7200/7250
Q-TOF GC/MS due to the vibration that the pump creates. Vibration can lead to a loss of
mass accuracy and resolution.

NOTE
Installation Kits
Installation Kits
Installation kits are not supplied with the GC. If you did not order the GC with the factory
plumbing option (305), Agilent highly recommends the following kits in Table 2.
•Agilent recommends purchasing the installation kit(s) that provides parts useful for GC
installation. (Tab le 2 lists the appropriate installation kits.)
In addition to these installation kits, fittings and reducers are required to convert gas cylinder
regulator fittings (for example, 1/4-inch male NPT) to the 1/8-inch female Swagelok fittings
needed to connect gases to the instrument. These fittings are not included with the GC or with
the installation kits. See “Gas Plumbing” on page 49 for details.
