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.
Table 57 lists available Agilent two- stage tank regulators. All Agilent
regulators are supplied with the 1/8- inch Swagelok female connector.
Table 58 and Table 59 list minimum and maximum delivery pressures for
inlets and detectors, measured at the bulkhead fittings on the back of the
instrument.
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.
