Installation of the separating column without suppressor
module «MSM II»
With the 2.861.0010 Compact IC without suppressor module «MSM II»,
the IC separating column is installed as follows (see Figure 14):
1 Connect column to injection valve
•
Remove end caps from column 73.
•
without precolumn:
Screw inlet end of separating column 73 (note flow direction)
to column connection capillary 26 mounted on the injection
valve.
•
with precolumn:
See relevant leaflet.
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>
.
3 Connect column to detector block
•
Screw outlet end of separating column 73 to the inlet capillary
44 permanently mounted on the detector block 45.
4 Column attachment
•
Insert one or two column holders 74 (6.2027.030, 6.2027.040
or 6.2027.050) in the mounting rails 25 and fasten separating
column 73 in the column holder 74.
