2.4.5 Auxiliary Valve (Optional)
The auxiliary valve is a high-pressure Rheodyne valve. The electrically-
activated, 2-position PEEK valve is offered in both 6-port and 10-port
models (6-Port Valve Kit, P/N 069472; 10-Port Valve Kit, P/N 069473).
The auxiliary valve enables a variety of sample preparation activities,
including:
•
Online filtration
•
Matrix elimination (for example, the removal of high backgrounds of
chloride or organic material)
•
Concentrator-based techniques
•
Conditional injections (large loop/small loop applications where the
data system monitors sample concentration and reinjects the sample,
using the smaller loop, if the concentration is too high)
•
AutoNeutralization
™
•
Matrix diversion prior to MS (mass spectrometry) detection
For more information, refer to Installing the ICS-1100/ICS-1600/ICS-
2100 Auxiliary Valve (Document No. 065288). The manual is provided in
the Auxiliary Valve Kit.
