2.13.3 10-Port Valve
The 10-port valve (P/N 061962) is an optional valve, available for various
applications.
Figure 2-26 shows example flow schematics for the 10-port
valve when it is connected for an application that uses a concentrator column.
NOTE
Other plumbing configurations for the 10-port valve are pos-
sible, depending on the components to be connected to the
valve and the application to be run. Refer to the appropriate
Application Note for more information.
Liquid flows through either the Load or Inject path, depending on the valve
position. For the example shown in
Figure 2-26 , the flow occurs as follows:
•
In the Load position, sample flows from the syringe or autosampler line,
through the valve, and into the sample loop. Excess sample flows out to
waste. Eluent flows from the eluent pump, through the valve, through the
concentrator column, and to the separator column. If sample was
previously loaded onto the concentrator column, it is swept to the
separator column for analysis.
