Conductivity detector
The conductivity detector continuously measures the conductivity of the
liquid passing through and indicates these signals in digital form (DSP –
Digital Signal Processing). The conductivity detector exhibits outstanding
thermal stability and thus guarantees reproducible measuring conditions.

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.

Intended use

The 850 Professional IC – Anion – MSM-HC – MCS – Prep 3 is used
for ion chromatographic determination of anions with sequential sup-
pression
and inline sample preparation:

Sequential suppression consists of:

Chemical suppression by the High Capacity Metrohm Suppressor Mod-
ule (MSM-HC) (see Chapter 3.18, page 62) and subsequent

CO

suppression by the Metrohm CO

2

Suppressor (MCS) (see Chapter

3.19, page 65).

The use of this technology reduces background conductivity to a mini-
mum and improves the detection accuracy.

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
– Prep 3 therefore requires that the user has basic knowledge and experi-
ence 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.
