1 Introduction
1.1 Instrument description
The 896 Professional Detector – Conductivity is an intelligent Stand-
Alone Detector equipped with a high-performance conductivity detector.
As a stand-alone detector, it can for example be combined with instru-
ments of the 850 Professional IC family for which all available detector
connectors have already been assigned to conductivity detectors (AnCat
systems or other multi-channel systems) when an additional conductivity
detector is required.
AnCat systems or other multi-channel systems can be implemented with
the 896 Professional Detector – Conductivity, even with the instruments
of the Compact IC family (881 and 882) and with the 883 Basic IC plus,
which possess only one detector connector which would normally be
occupied by a conductivity detector.
872 Extension Modules, 891 Analog Out and 800 Dosinos, Remote Boxes,
etc. can all be operated through the 896 Professional Detector – Conduc-
tivity. This opens up the flexibility of Metrohm IC systems considerably.
The instrument is comprised of the following modules:
Conductivity detector
The conductivity detector continuously measures the conductivity of the
liquid passing through and indicates the measured values in digital form
(DSP – Digital Signal Processing). The conductivity detector exhibits out-
standing thermal stability and thus guarantees reproducible measuring
conditions.
1.2 Intended use
The 896 Professional Detector – Conductivity is used as an independent
conductivity detector in an IC system. It is used for the precise measure-
ment of the conductivity during the ion chromatographic determination of
cations and anions.
The present instrument is used for working with chemicals and flammable
samples. Usage of the 896 Professional Detector – Conductivity therefore
requires the user to have basic knowledge and experience in the handling
of toxic and caustic substances. Knowledge with respect to the applica-
tion of the fire prevention measures prescribed for laboratories is also
mandatory.
