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.
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 882 Compact IC plus – Cation is used for the ion chromatographic
determination of cations or anions (without chemical suppression).
This instrument is suitable for processing chemicals and flammable sam-
ples. The usage of the 882 Compact IC plus – Cation 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.
