Figure 2-8 and Figure 2-9 show the flow schematics for the 6-port and 10-
port valves.
Operation as an Application Valve
The optional valve can be configured for various application functions,
including sample injection, concentrator column loading, or matrix
elimination.
Plumbing configurations for the valves depend on the components to be
connected and the application to be run. Refer to the appropriate Thermo
Scientific Dionex Application Note for more information.
Operation as a Bleed Valve
When the optional valve is configured as a bleed valve (see Figure 2-10
and Figure 2-11 ), the valve directs excess sample and any air trapped in
the sample vial to waste. Excess sample is any sample above the fill line
on the vial (see
Figure 2-7 ). After the initial bleed, the valve position is
switched and the sample is sent directly to the injection valve in the IC
system.
