Introduction
General
This document describes the configuration procedure of the
Varian ProStar 220, 230, and 240 pump driver. It also explains
how to build a control method for this driver, how to start and
view a running acquisition and what actions are available during
an analysis.
The ProStar 220, 230 and 240 Solvent Delivery modules are
single piston pumps which deliver flow in a linear dynamic range.
The 220 is designed for isocratic (single solvent) applications
only.
Proportioned delivery of multiple solvents can be achieved by the
230 and 240 pumps. Up to 3 solvents may be run isocratically or
in gradients with the ProStar 230 SDM. The 240 SDM is a
quaternary HPLC system which allows the user to run any of four
solvents isocratically or to proportion, and run a gradient with
three solvents.
