2.7.8 Installation of the separating column with suppressor
With the 2.761.0020 Compact IC with suppressor module, the IC sepa-
rating column is first connected to the injector or precolumn. The con-
nection to the suppressor module and the detector block is described
in section 2.8.
1 Connect column to injector
• Remove end caps from column 81.
• Screw inlet end of separating column 81 (note flow direction)
to column connection capillary 28 or to the already installed
precolumn (procedure see section 2.7.7).
2 Rinse column
• Place a beaker beneath the column outlet.
• Open software window for manual system control.
• If necessary, modify Flow rate to the value suited for the
inserted separating column and click on to
send this value to the 761 Compact IC.
• Switch on high-pressure pump ( IC pump ) by clicking
and rinse column with eluent for ca. 10 min.
• Switch off high-pressure pump by clicking .
3 Fix column
• Insert one or two column holders 88 (6.2027.030, 6.2027.040
