4.10 Second Conductivity Monitor - GE AKTA avant User Manual

4.10 Second Conductivity monitor

Introduction
It is possible to use two conductivity monitors. The second Conductivity monitor could
for example be placed before the column for extended gradient control or on a sample
inlet line for control of ionic strength in the sample.
Location
The recommended position of the second Conductivity monitor is dependent on column
size or where the Sample inlet valve is placed. The nearest empty module position should
be used. It is possible to install the module in an Extension box. See Section 2.6.3 Extension
box, on page 53.
Connect tubing
When connecting a second Conductivity monitor to ÄKTA avant use the tubing dimensions
that are most suitable for the chosen location and application.
