1.2 Intended use
The instrument 850 Professional IC – Anion – MCS – Prep 3 is used
for ion chromatographic determination of anions or polar substances with
sequential suppression:

minimum.
If required, the instrument can also be used for the determination of cati-
ons or anions without suppression.
The peristaltic pump and the sample preparation module (SPM) (see Chap-
ter 2.14, page 40) in the lower part of the instrument are used for the
inline sample preparation – e.g. for or .
