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 – Anion – MSM-HC – MCS – Gradient is
used for the ion chromatography determination of anions with binary
high pressure gradient and sequential suppression:
Sequential suppression consists of:
￭ Chemical suppression by the Metrohm Suppressor Module (MSM) and
subsequent
￭ CO
2
suppression by the Metrohm CO
2
Suppressor (MCS) (see Chapter
3.18, page 60).
The use of this technology reduces background conductivity to an abso-
lute minimum.
If required, the instrument can also be used for the determination of cati-
ons and anions without suppression.
The present instrument is suitable for processing chemicals and flammable
samples. The usage of the 850 Professional IC – Anion – MSM-HC – MCS
– Gradient therefore requires that the user has basic knowledge and expe-
rience 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.
