5 You should also refer to thischecklist forsupplies that you need to operate yourGC, such as traps and tubing. You canfind more site preparation information inthis Preparation Checklist The site is well ventilated and free of corrosive materials and overhanging obstacles. Site temperature is within the recommended range of 20 to 27EC. Site humidity is within the recommended range of 50 to 60%. Bench space is adequate for the GC with EPC: 50 cm x cm x 50 cm (21 in. x 23 in. x 21 in.)Bench space is adequate for the GC without EPC: 50 cm x 68 cm x 50 cm (21 in. x in. x 21 in.) Bench can support the weight of the HP 6890 system. Power receptacle is earth grounded. Electrical supply meets allGC s power requirements; see page 10. Voltage supply is adequate for oven oven:2,250 oven:2,950 VA. Gas supplies meet the requirements of your columns and detectors; see page 12. Gases meet purity requirements. All should be chromatographic-grade pure or should be zero-grade or better.

6 Obtained precleaned, 1/8-inch copper tubing for inlet and detector gas supplies: Inlet and detector gas supplies have two-stage pressure regulators installed (optional). Obtained traps for inlet and detector gas supplies molecular sieve trap, hydrocarbon trap, and/or oxygentrap. Obtained liquid N2or liquid CO2(depending on requirements) for cryogenic cooling. Obtained 1/4-inch insulated copper tubing for liquid N2suppliesOR1/8-inch heavy-walled, stainless steeltubing for liquid CO2supplies. Obtained insulation for liquid N2tubing. Obtained air for valve PreparationSite preparation involves two general steps: insuring that yourlaboratory is capable of supporting the operation of the GC and obtainingsupplies and tools you will need to install the instrument. A list of thenecessary tools and supplies appears at the beginning of the Installation chapter. Most supplies are available fromHewlett-Packard. See the HP Analytical Direct Analytical Columns andSupplies catalog for descriptions and ordering information.

Warmed air exits through slots in the top,rear, and side panels. Do not obstruct air flow around the proper cooling and general safety, always operate the instrumentwith cover panels properly oven exhaustHot air (up to 450EC) from the oven exits through a vent in the at least 20 cm (10 in.) clearance behind the instrument todissipate this not place temperature-sensitive items (for example, gas cylinders,chemicals, or regulators) in the path of the heated exhaust.

8 Be carefulwhen working behind the instrument during cool-down cycles to avoidburns from the hot space is limited, the Oven Exhaust Deflector (HP part ) may improve oven cooling. It diverts exhaust air up andaway from the instrument. You can connect it to a (4-in.)exhaust-duct system, route the exhaust to a fume hood, or vent theexhaust outside the building with diameter (4-inch diameter)furnace toxic or noxious gasesDuring normal operation of the GC with many detectors and inlets, someof the carrier gas and sample vents outside the instrument. If anysample components are toxic or noxious, or if hydrogen is used as thecarrier gas, the exhaust must be vented to a fume hood. Place the GC inthe hood or attach a large diameter venting tube to the outlet for further prevent contamination from noxious gases, you can attach achemical trap to the split Preparation5 Benchtop space requirementsThe GC with electronic pneumatics control (EPC) is 59 cm (23 in.)

9 NonEPC model is 68 cm ( in.) wide. Both are 50 cm (21 in.) highand 50 cm (21 in.) area above the GC should be clear, with no shelves or overhangingobstructions that limit access to the top of the instrument and interferewith cooling. You may need additional space for other instruments usedwith your GC. Figure 1 shows some common system 1 presents the dimensions, voltage requirements, heat production,and weight of the GC and other Hewlett-Packard instruments often usedwith it. Use this table to insure that you have adequate space and powerfor the entire system. Allow at least cm (4 in.) space betweeninstruments for Preparation6 Figure 1.
