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.
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.
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
This instrument is suitable for processing chemicals and flammable sam-
ples. The usage of the 881 Compact IC pro – 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.
