Gas Supplies - Agilent Technologies ALS Handbuch

Gas Supplies

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.
Plumb the gas supply tubing/regulators so that one 1/8-inch Swagelok female connector is
N O T E
available for each gas needed at the instrument.

regulators are supplied with the 1/8-inch Swagelok female connector.
