882 Compact IC plus – Anion – MCS
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 with conduc-
tivity detection or UV detection.It is pressure-stable, robust and resistant
to solvents.
Metrohm CO
2
Suppressor (MCS)
The Metrohm CO
2
Suppressor (MCS) removes the CO
2
from the eluent
flow. This reduces the background conductivity, improves the detection
sensitivity and minimizes the injection and carbonate peaks.
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.
