Inlet Valves
The inlet valves automate the use of multiple buffers and samples during method
development. In ChromLab, you can program the inlet valves to
 Switch between buffers during a method run
 Automate sample selection and loading by way of the sample pump
 Switch between cleaning solutions and buffers during system wash and
preparation
The inlet valve has eight defined inlet ports and one outlet port. The active ports are
identified by green LEDs for the buffer inlet valve and blue LEDs for the sample inlet
valve. In ChromLab you can provide a custom label for each port to easily identify it
during method protocol programming.
Tip: In Manual mode (accessed from the System Control tab in ChromLab),
you can select a specific port on the buffer inlet valve through its dialog box. To
open the dialog box, touch or click the inlet valve in the fluidic scheme. When
the buffer blending valve is present, touch or click the pump/valve module to
access the positions on the buffer inlet valves. To access the positions on the
sample inlet valves, touch or click the sample pump module in the fluidic
scheme.
