￭ Connect the other end of the 6.1831.100 connection capillary
(12-2)/(13-2) either with
– a 6.2744.070 pressure screw to the T distributor (12-7) of
the gradient mixing coil (gradient system)
or
– a 6.2744.014 pressure screw to the injection valve of the
850 Professional IC instrument (isocratic system).

￭ Put IC instrument into operation together with extension module
￭ Deaerate the high pressure pump (see Chapter 4.6.2, page 32).
4.3 Installation diagram
The 872 Extension Module – IC Pump can be used as an additional pump
for a high pressure gradient system or it can extend an 850 Professional IC
instrument with an additional isocratic channel. The following installation
diagrams show the capillary connections for these two possible applica-
tions.
Figure 12: Installation diagram – gradient shows the capillary connections
of the 872 Extension Module IC Pump used as component of a high pres-
sure gradient system.
Figure 13: Installation diagram – isocratic shows the capillary connections
of the 872 Extension Module IC Pump used as additional isocratic pump.
The arrangement of the modules in the diagram corresponds to the front
view of the extension module. Liquid containers are not shown in the dia-
gram.
A few of the capillaries are already pre-installed at the time the instrument
is delivered. Capillaries on which nothing needs to be done at the time of
initial installation are not numbered in the diagram.
