Up to three extension modules can be connected to an 850 Professional
IC instrument. The following restrictions are to be taken into account:
Restrictions
The 850 Professional IC instruments and their extension modules must not
have more than 4 identical components in common, i.e.:
■
a maximum of 4 high pressure pumps,
■
a maximum of 4 peristaltic pumps,
■
a maximum of 4 injection valves,
■
a maximum of 4 suppressors (MSM, SPM incl.),
BUT
■
only a maximum of 3 degassers
■
and a maximum of 3 CO
2
suppressors (MCS)
Note
If all 4 high pressure pumps are being used at once, then not all of
them are permitted to run at maximum flow for longer periods of time.
Position the extension module in such a way that the capillary connections
can be kept as short as possible. If several extension modules are used,
then they should all be installed in the same location, either on top or
below. If this is not possible, then the extension modules that are located
at greater distances from one another must be connected with one
another by means of the longer 6.2156.070 connection cable.
