The
Waters 590 Programmable Pump is a high performance pump designed specifically
for liquid chromatography applications. A computerized
electronics unit allow either manual or automatic control of the
operating conditions. Flow rate may be set from 0.001 to 20.00 ml/min (up to 45
ml/min with the extended flow heads) in increments of 0.001 ml/min, and a
method program may contain up to 40 different flow rate operations (segments).
Compressibility compensation values may also be entered into the system to maintain
accuracy at high pressures.
