2.7.5 Installation of the separating column with suppressor
module «MSM II»
With the versions 2.861.0020 and 2.861.0040 Compact IC with sup-
pressor module «MSM II», the IC separating column is first connected to
the injection valve or precolumn. The connection to the suppressor
module «MSM II» and the detector block is described in Section 2.8.
1 Connect column to injection valve
• Remove end caps from column 73.
• Screw inlet end of separating column 73 (note flow direction)
to column connection capillary 26 or to the already installed
precolumn (procedure see Section 2.7.4).
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 inser-
ted separating column and click on <Send to unit> to send this
value to the 861 Advanced Compact IC.
• Switch on high-pressure pump ( IC pump ) by clicking <On>
and rinse column with eluent for approx. 10 min.
• Switch off high-pressure pump by clicking <Off> .
