Page 8: Computer Requirements
7820A GC Site Preparation Computer Requirements A computer is required for 7820A GC installation and operation. The computer must meet the minimum requirements to run the Agilent Instrument Utility. Table 1 lists these requirements for version B.01.01 of the Instrument Utility. -
Page 9: Dimensions And Weight
Computer with monitor Printer Figure 1 Top view of typical installation (7820A GC system) A simple 7820A system that includes a GC, ALS injector, and a computer would require about 111 cm (3 ft 8 in.) of bench space. Allowing for operational access and a printer, a total of 153 cm (5 ft) of bench space should be available for a full GC system. -
Page 10: Power Consumption
Although your GC should arrive ready for operation in your country, compare its voltage requirements with those listed in Table 3. If the voltage option you ordered is not suitable for your installation, contact Agilent Technologies. 7820A GC Site Preparation Guide... -
Page 11: Grounding
A properly grounded receptacle is one that is connected to a suitable earth ground. Be sure to verify proper receptacle grounding. Connect the GC to a dedicated receptacle. Use of a dedicated receptacle reduces interference. 7820A GC Site Preparation Guide... -

Page 19: Gas Plumbing
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. 7820A GC Site Preparation Guide... -
Page 20: Supply Tubing For Carrier And Detector Gases
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. 7820A GC Site Preparation Guide... -
Page 21: Two-Stage Pressure Regulators
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 ®... -
Page 22: Traps
Place it last in a series of traps. Because trace amounts of oxygen can damage columns and degrade uECD performance, use an oxygen trap with carrier and uECD gases. Do not use it with FID or NPD fuel gases. 7820A GC Site Preparation Guide... -

• The length of the Agilent-supplied remote cable is 2 meters (6.6 feet). • The length of the Agilent-supplied LAN cable is 10 meters (32.8 feet). • The lengths of the power cords are 2 meters (6.6 feet). 7820A GC Site Preparation Guide... -
Page 24: Site Lan Network
If you intend to connect your system to your site’s LAN network, you must have an additional shielded twisted pair network cable. Agilent Technologies is not responsible for connecting to or establishing N O T E communication with your site LAN network. The representative will test the system’s ability to communicate on a mini-hub or LAN switch only. -
