7890 Series GC Site Preparation WA R N I N G Do not use extension cords with Agilent instruments. Extension cords normally are not rated to carry enough power and can be a safety hazard. 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. Note that ALS instruments receive their power from the GC.
7890 Series GC Site Preparation 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).

7890 Series GC Site Preparation Heat Dissipation Use Table 5 to estimate the additional BTUs of heat dissipated from this equipment. Maximums represent the heat given off when heated zones are set for maximum temperatures.
7890 Series GC Site Preparation Exhaust Venting Hot air (up to 450 °C) from the oven exits through a vent in the rear. Allow at least 25 cm (10 in) clearance behind the instrument, or 30 cm (12 in) behind a Q- TOF GC/MS, and 76 cm (30 in) above the Ion Trap to dissipate this air. WA R N I N G 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.
7890 Series GC Site Preparation Figure 4 Exhaust deflector G1530-80650 During normal operation of the GC with many detectors and inlets, 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, these exhausts must be vented to a fume hood. Place the GC in the hood or attach a large diameter venting tube to the outlet for proper ventilation.
7890 Series GC Site Preparation Environmental Conditions Operating the instrument within the recommended ranges optimizes instrument performance and lifetime. Performance can be affected by sources of heat and cold from heating, air conditioning systems, or drafts. See Table 6. The conditions assume a noncondensing, noncorrosive atmosphere.

7890 Series GC Site Preparation Gas and Reagent Selection Table 7 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 using any MS system, use of hydrogen as the carrier gas may require hardware modifications for best performance. Contact your Agilent service representative. Hydrogen is not supported as a carrier gas with the 7200 GC/QTOF system.
7890 Series GC Site Preparation Table 8 lists gas recommendations for packed column use. In general, makeup gases are not required with packed columns.

7890 Series GC Site Preparation Gas and Reagent Purity Agilent recommends that carrier and detector gases be 99.9995% pure. See Table 10. Air needs to be zero grade or better. Agilent also recommends using high quality traps to remove hydrocarbons, water, and oxygen. Table 10 Carrier, collision, and reagent gas purity Carrier, collision, and reagent gas requirements Purity Notes Helium (carrier and collision) 99.9995% Hydrocarbon free Hydrogen (carrier) 99.9995% SFC grade 99.
7890 Series GC Site Preparation Gas Supplies General requirements Supply instrument gases using tanks, an internal distribution system, or gas generators. If used, tanks require two- stage pressure regulators with packless, stainless steel diaphragms. The instrument requires 1/8- inch Swagelok connections to its gas supply fittings. NOTE Plumb the gas supply tubing/regulators so that one 1/8-inch Swagelok female connector is available for each gas needed at the instrument.

7890 Series GC Site Preparation Requirements for hydrogen as a carrier gas Not all systems can use hydrogen as a carrier gas. See Gas and Reagent 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.

7890 Series GC Site Preparation 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. WA R N I N G 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. Two-stage regulation On/off valve Main supply on/off valve Gas Clean filter system.
7890 Series GC Site Preparation • 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.
7890 Series GC Site Preparation 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. CAUTION 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.
7890 Series GC Site Preparation • 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 output as high background noise or hydrocarbon contamination for several weeks. • Especially do not use old copper tubing, which can become brittle. WA R N I N G Do not use old copper tubing with hydrogen gas.
7890 Series GC Site Preparation 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.
7890 Series GC Site Preparation 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.

7890 Series GC Site Preparation Cryogenic Cooling Requirements Cryogenic cooling allows you to cool the oven or inlet, including cooling to setpoints below ambient temperature. A solenoid valve controls the flow of coolant to the inlet or oven. The oven can use either liquid carbon dioxide (CO2) or liquid nitrogen (N2) as a coolant. All inlets except the multimode inlet must use the same coolant type as the oven.
7890 Series GC Site Preparation WA R N I N G Do not use copper tubing or thin-wall stainless steel tubing with liquid CO2. Both harden at stress points and may explode. Additional requirements for the liquid CO2 system include: • The tank must have an internal dip tube or eductor tube to deliver liquid CO2 instead of gas (see the figure below). • Typical liquid CO2 tank pressure will be 4830 to 6900 kPa (700 to 1,000 psi) at a temperature of 25 °C.
7890 Series GC Site Preparation Using liquid nitrogen WA R N I N G Liquid nitrogen is a hazard because of the extremely low temperatures and high pressures that may occur in improperly designed supply systems. Liquid nitrogen can present an asphyxiant hazard if vaporizing nitrogen displaces oxygen in the air. Consult local suppliers for safety precautions and design information. Liquid nitrogen is supplied in insulated Dewar tanks.
7890 Series GC Site Preparation Using compressed air The multimode inlet can also use compressed air cooling with the liquid N2 inlet cooling option. Requirements for compressed air cooling: • The compressed air should be free of particulate material, oil, and other contaminants. These contaminants could clog the inlet's cryo valve and expansion orifice or impact the proper operation of the GC. • The required air supply pressure depends on the installed solenoid valve type.
7890 Series GC Site Preparation Maximum Length of Cables and Hoses The distance between system modules may be limited by some of the cabling and the vent or vacuum hoses. • 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). • A quadrupole GC/MS system foreline pump can be located on the laboratory bench or on the floor.
7890 Series GC Site Preparation 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 (8121- 0940). NOTE Agilent Technologies is not responsible for connecting to or establishing communication with your site LAN network. The representative will test the system’s ability to communicate on a mini-hub or LAN switch only.

6850 Series GC Site Preparation 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. WA R N I N G 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. Two-stage regulation On/off valve Main supply on/off valve Main gas supply Gas Clean filter system.
6850 Series GC Site Preparation • 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.
6850 Series GC Site Preparation 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. CAUTION 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.
6850 Series GC Site Preparation • 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 output as high background noise or hydrocarbon contamination for several weeks. • Especially do not use old copper tubing, which can become brittle. WA R N I N G Do not use old copper tubing with hydrogen gas.
6850 Series GC Site Preparation 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.
6850 Series GC Site Preparation 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).

6850 Series GC Site Preparation Cryogenic Cooling Requirements Cryogenic cooling allows you to cool the oven or inlet, including cooling to setpoints below ambient temperature. A solenoid valve controls the flow of coolant to the inlet or oven. The oven and inlet can use liquid carbon dioxide (CO2) as a coolant. Using carbon dioxide WA R N I N G Pressurized liquid CO2 is a hazardous material. Take precautions to protect personnel from high pressures and low temperatures.
6850 Series GC Site Preparation • Use 1/8- inch diameter heavy- wall stainless steel tubing for supply tubing. The tubing should be between 1.5 and 15 m (5 and 50 feet) long. (Agilent part number 7157- 0210, 20 ft) • Coil and fasten the ends of the tubing to prevent it from “whipping” if it breaks. • Do not install a pressure regulator on the CO2 tank, as vaporization and cooling would occur in the regulator instead of the oven.
6850 Series GC Site Preparation Maximum Length of Cables The distance between system modules may be limited by some of the cabling and the vent or vacuum hoses. • 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). • A quadrupole GC/MS system foreline pump can be located on the laboratory bench or on the floor.
6850 Series GC Site Preparation 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 (8121- 0940). 98 NOTE Agilent Technologies is not responsible for connecting to or establishing communication with your site LAN network.
