Qualified Computer EquipmentIf you need to install the Varian <strong>MS</strong> W<strong>or</strong>kstation software on a computer not purchasedfrom Varian, you must ensure that the computer is adequately equipped and compatiblewith the operation of data system and its communication interfaces of the data system.Consult the current list of requirements, available at this web site.http://www.varianinc.com/cgi-bin/nav?products/chrom/gcms/msws _ computer _ reqThe Varian Representative uses only a Varian qualified computer when testing the systemspecifications. Varian does not guarantee the function of the Varian <strong>MS</strong> W<strong>or</strong>kstation software onany other computer hardware <strong>or</strong> operating systems.NOTE: Contact your Sales Representative f<strong>or</strong> a list of the currently qualified equipment <strong>or</strong> m<strong>or</strong>einf<strong>or</strong>mation.Gas RequirementsChemical <strong>Ion</strong>ization Reagent GasesThe Chemical <strong>Ion</strong>ization (CI) mode uses methane, isobutane, <strong>or</strong> ammonia as a reagent gas f<strong>or</strong>CI operation consumes approximately 1 to 2 mL/min. The CI reagent gas should contain lessthan 1 ppm water. The methane, isobutane, <strong>or</strong> ammonia supply line connects directly to the CIgas inlet using 1/8 inch Swagelok® fittings.New gas lines typically contain significant amounts of ads<strong>or</strong>bed water vap<strong>or</strong>. Pump air throughthe gas line to evacuate the water. Use the sh<strong>or</strong>test gas line possible to minimize pumping time.Methane 99.99% purity• Use a two-stage, 0-15 psi (0-1 bar) pressure regulat<strong>or</strong> with a stainless steel diaphragm.• Set the output pressure to the <strong>MS</strong> between 3 and 5 psi (0.2-0.3 bar).• Use stainless steel gas lines f<strong>or</strong> methane.• Flame treat <strong>or</strong> solvent wash gas lines to remove oil.Isobutane 99.99% purity• Use a two-stage, 0-15 psi (0-1 bar) pressure regulat<strong>or</strong> with a stainless steel diaphragm.• Set the output pressure to the <strong>MS</strong> between 3 and 5 psi (0.2-0.3 bar).• Use stainless steel gas lines f<strong>or</strong> isobutane.• Flame treat <strong>or</strong> solvent wash gas lines to remove oil.Ammonia 99.99% purity• Use a two-stage, 0-15 psi (0-1 bar) pressure regulat<strong>or</strong> with a stainless steel diaphragm.• Set the output pressure to the <strong>MS</strong> between 3 and 5 psi (0.2-0.3 bar).• Use stainless steel gas lines f<strong>or</strong> ammonia.• Flame treat <strong>or</strong> solvent wash gas lines to remove oil.395414200:5 11 of 14 <strong>Pre</strong>-installation Instructions
