Pulsation absorber
The pulsation absorber 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.
Peristaltic pump
The Peristaltic pump is used for pumping sample and auxiliary solutions. It
can rotate in both directions.
Metrohm Suppressor Module (MSM)
The MSM is used for chemical suppression in anion analysis.It is pressure-
stable, robust and resistant to solvents.
Separation column
The intelligent separation column is the heart of the ion chromatographic
analysis. It separates the different components corresponding to their
interactions with the column. Metrohm separation columns are equipped
with a chip on which their technical specifications and their history (first
use / setting up, operating hours, injections, …) are saved.
1.2 Intended use
The instrument 882 Compact IC plus – Anion is used for the ion chro-
matographic determination of anions or polar substances with chemical
suppression by the Metrohm Suppressor Module (MSM) (see Chapter
3.14, page 42). If required, it can also be used for the determination of
anions without chemical suppression or for the determination of cations.
This instrument is suitable for processing chemicals and flammable sam-
ples. The usage of the 882 Compact IC plusAnion 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.
