1.2 Intended use
The instrument 850 Professional IC – Anion – MCS – Prep 2 is used
for ion chromatographic determination of anions or polar substances with
sequential suppression:
￭ Chemical suppression with the Metrohm Suppressor Module (MSM)
(see Chapter 2.16, page 50) and subsequent
￭ CO
2
suppression with the Metrohm CO
2
Suppressor (MCS) (see Chap-
ter 2.18, page 58).
The use of sequential suppression reduces background conductivity to a
minimum.
If required, the instrument can also be used for the determination of cati-
ons or anions without suppression.
The peristaltic pump and the additional injection valve in the lower area of
the instrument are used for inline sample preparation and calibration tech-
niques – e.g. Matrix elimination with transfer procedure or Standard
addition with preconcentration. For sample dilution Metrohm offers a
special equipment (6.5330.020).
The present instrument is suitable for processing chemicals and flammable
samples. The usage of the 850 Professional IC – Anion – MCS – Prep 2
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.
