2.13 High-Pressure Valves
Up to four high-pressure valves can be installed in the DC. The following
valve models are available: 4-port (P/N 074525), 6-port (P/N 061961), and
10-port (P/N 061962).
In a capillary IC system, one 4-port high-pressure valve is installed on each IC
Cube. This valve is used for sample injection. Optionally, the 6-port valve can
be installed instead of the 4-port valve. In addition to the injection valve, one
or two high-pressure valves can be installed in the lower compartment. These
valves can be used for applications requiring auxiliary valves.
In an analytical IC system, one 6-port high-pressure valve is installed in the
lower compartment for each system configured in the DC.This valve is used
for sample injection. Optionally, one or two high-pressure valves can be
installed on an AM (see
Section 2.18 ). These valves can be used for
applications requiring auxiliary valves.
Each valve has two operating positions. When configured as an injection
valve, liquid flows through either the Load or Inject path, depending on the
valve position. In the Load position, sample is loaded into the sample loop. In
the Inject position, sample is swept to the column for analysis.
When configured as an auxiliary valve, the flow path through system
components in each valve position depends on the component configuration.
