Two-stage pressure regulators

Two stages of pressure regulation are needed to reduce the very high
source pressure to the pressures used by the instrument. The two stages
may be combined in a single regulator with a fairly short tubing run to
the instrument, or one stage may be at the source with the second stage
close to the instrument. In either case, use good quality regulators with
stainless steel diaphragms. See the Hewlett•Packard's analytical
supplies catalog for further information.

Molecular sieve moisture trap

A type A molecular sieve moisture trap is supplied with ECDs. Install it
between the carrier gas source regulator and inlet supply fitting on the
instrument.

Moisture in the carrier gas can damage columns. We recommend
moisture traps for all carrier gases, regardless of the detector, and also
for detector support gases (makeup, hydrogen, air).

Oxygen trap

Trace amounts of oxygen can damage columns, particularly capillary
columns. Oxygen also degrades the performance of ECDs. An oxygen trap
may be connected between the molecular sieve drier and inlet supply
fittings to the instrument.
