3.4 Inlet valves
Introduction
The inlet valves are used to select which buffers or samples to use in a run.
Inlet valve A is located before System pump A, Inlet valve B is located before System
pump B, and the Sample inlet valve is located before the Sample pump. Inlet valve A and
Inlet valve B are connected to the Quaternary valve. The Quaternary valve is used for
automatic buffer preparation in BufferPro, and for formation of quaternary gradients.
The number of inlets can be increased by installing extra inlet valves. For information
on how to install extra valves, please refer to Section 4.1 System extension overview, on
page 101.
This section describes the location and function of the inlet valves.
