Use the eluent from the conductivity detector as a rinsing solution.
￭ Rinsing solution via peristaltic pump
Prepare the rinsing solution in its own bottle and transport with the
peristaltic pump.
The rinsing solution is connected to the rinsing solution capillary.
Connecting the rinsing solution inlet with STREAM
1 Connect the detector output capillary and the capillary labeled rins-
ing solution to each other using a coupling (6.2744.040) and two
pressure screws (6.2744.070).
