872 Extension Module IC Module
Inline filter
Inline filters protect the separation column securely against possible con-
tamination from the eluent. Inline filters can however also just as well be
used for the purpose of protecting other sensitive components against
contaminations in the solutions used. The fine 2 µm material of the readily
and easily replaceable filter platelets removes particles such as bacteria
and algae from the solutions.
Pulsation damper
The pulsation damper protects the separation column from damage
caused by pressure fluctuations when switching the injection valve, and
reduces interfering pulsations during highly sensitive measurements.
Injection valve
The injection valve connects the eluent and sample path through rapid
and precise valve switchover. A precisely measured amount of sample
solution is injected and rinsed with eluent onto the separation column.
1.2 Intended use
The present instrument is suitable for processing chemicals and flammable
samples. The usage of the 872 Extension Module therefore requires that
the user has basic knowledge and experience in the handling of toxic and
caustic substances. Knowledge with respect to the application of the fire
prevention measures prescribed for laboratories is also mandatory.
1.3 About the documentation
1.3.1 Content and scope
This document describes the 872 Extension Module – IC Module, its
assembly and connection to the IC instrument, as well as the installation,
operation and maintenance of the individual components. Technical speci-
fications, troubleshooting and information concerning scope of delivery
and optional accessories makes up the rest of the manual.
This document does not on the other hand describe the functions of the
IC instrument - IC extension module unit, nor does it describe the capillary
connections that proceed from the extension module. For this purpose,
please refer to the manual for the IC instrument and that for the sample
processor.
