850 Professional IC Cation – HP-Gradient
used for the purpose of protecting other sensitive components against
contaminations in the solutions used. The fine 2 µm material of the readily
and easily replaceable filter platelets removes particles such as bacteria
and algae from the solutions.
Pulsation damper
The pulsation damper 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 disolved 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 thermostat
The column thermostat controls the temperature of the column and elu-
ent channel and thus ensures stable measuring conditions. It provides
space for 2 separation columns.
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. The Metrohm analytical columns are equip-
ped 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 850 Professional IC Cation – HP-Gradient is used for the ion
chromatographic determination of cations with binary high pressure
gradient.
If required, the instrument can also be used for the determination of cati-
ons or anions without suppression.
This instrument is suitable for processing chemicals and flammable sam-
ples. The usage of the 850 Professional IC Cation – HP-Gradient therefore
requires that the user has basic knowledge and experience in the handling
of toxic and caustic substances. Knowledge with respect to the applica-
tion of the fire prevention measures prescribed for laboratories is also
mandatory.
