Rinse Connections Using the Existing Peristaltic
Pump
For some applications, it may be possible to use the existing peristaltic pump
on an ASX-1400/1600 without an additional diaphragm pump.
In order to provide the necessary additional flow rate at the rinse station, the
pump speed must be increased.
1 On the back of the autosampler, turn the Main Pump Speed knob to its
maximum setting. See Figure 5-9.
Figure 5-9 Pump Speed
If you find the flow rate to be inadequate to keep up with the ASX
PRESS PLUS
Rapid Sample Introduction System, an additional pump may be required.
Contact CETAC Technologies for recommendations.
Remember to use Viton tubing (not PharMed) for the peristaltic pump tubing if
the rinse solution is kerosene.
