1.1 Instrument description
The instrument 850 Professional IC Anion MSM-HC LP Gradient
(2.850.2250) is one of the model versions of the Professional IC line of
instruments manufactured by the Metrohm Company. The Professional IC
line of instruments is distinguished by:
￭ the intelligence of its components, which are able to monitor and
optimize all functions and to provide documentation according to FDA
requirements.
￭ its compactness.
￭ its flexibility. A suitable model version exists for every application.
Individual instruments can be converted, expanded or modified to cre-
ate a different instrument as needed.
￭ its transparency. All components are easily accessible and arranged in
a clear manner.
￭ its safety. Chemicals and electronics are separated and a leak sensor is
integrated in the wet end.
￭ its environmental compatibility.
￭ low noise emission.
The instrument is operated with MagIC Net software. It is connected via
a USB connection to a PC on which MagIC Net is installed. The software
automatically recognizes the instrument and checks its functional readi-
ness. MagIC Net controls and monitors the instrument, evaluates the
measured data and administers it in a database. The operation of
MagIC Net is described in the online help or in the tutorial for MagIC Net.
The low pressure mixing valve and two additional eluent degassers in the
lower area of the instrument are used for the controlled mixing of up to 3
eluents.
The instrument contains the following components:
Eluent degasser
The eluent degasser removes gas bubbles and dissolved gases from the
eluent. For degassing, the eluent flows into a vacuum chamber through a
special fluoropolymer capillary.
Low pressure gradient
Up to three different eluents can be mixed with the low pressure gradient.
The mixing takes place in the low pressure zone, i.e. before the eluent is
conveyed to the high pressure pump.
