1 Introduction
1.1 Instrument description
Existing 850 Professional IC instruments can be expanded to include addi-
tional functions by means of 872 Extension Modules. Every 850 Professio-
nal IC instrument can be supplemented with up to 3 extension modules.
The 872 Extension ModuleSuppression – MCS permits to add an
additional suppression module to a Professional IC system.
The 872 Extension ModuleSuppression – MCS can be used wherever an
additional module for sequential suppression is necessary.
The extension module is operated with MagIC Net software, just like the
IC instrument. When it is connected to an 850 Professional IC instrument,
MagIC Net recognizes the extension module automatically and checks its
functional capability. It controls and monitors the unit IC instrument –
extension module, evaluates the measured data and administers it in a
database.
The 872 Extension ModuleSuppression – MCS comprises the following
components:
Peristaltic pump
The Peristaltic pump is used for pumping sample and auxiliary solutions. It
can rotate in both directions.
Suppressor drive
The suppressor drive allows you to flexibly use different rotors according
to the principle "one drive – many rotors". With appropriate adapters, the
rotor for the sample preparation module (SPM Rotor) or suppressor rotors
with different capacities and construction can be easily exchanged.
Metrohm CO
2
Suppressor (MCS)
The Metrohm CO
2
Suppressor (MCS) removes the CO
2
from the eluent
flow. This reduces the background conductivity, improves the detection
sensitivity and minimizes the injection and carbonate peaks.
