of 2 µm can be replaced quickly and easily. They remove particles like e. g.
bacteria and algae from the solutions.
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.
Sample degasser
The sample degasser removes gas bubbles and dissolved gases from the
sample. For degassing, the sample flows into a vacuum chamber through
a special fluoropolymer capillary.
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.
Column heater
The perfect isolation of the column chamber ensures thermally stable con-
ditions for the separation column. The temperature of the column heater
can be set in the software.
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.
