2 Connect new 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 precolumn (see
section 2.7.7/section 2.7.8).
3 Rinse column
Place beaker beneath the column outlet.
Switch on high-pressure pump and rinse column with eluent
for ca. 10 min, then switch off pump.
4 Connect column to detector block
Screw outlet end of separating column 81 to inlet capillary 45
or suppressor inlet capillary 96.
Changing the separation system
If you wish to replace an IC separating column by a column of a differ-
ent type, proceed as follows (see Fig. 14 and Fig. 16):
1 Remove old column
Switch off high-pressure pump and wait for pressure to drop.
Unscrew column 81 from inlet capillary 45 of the detector
block or from the suppressor inlet capillary 96.
Unscrew column 81 from column connection capillary 28 or
the precolumn.
2 Rinse with eluent
Place beaker beneath the column connection capillary 28.
Rinse IC system with eluent used for the separating column
(flow rate 1 mL/min) for ca. 15 min.
3 Connect new 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 precolumn (see
section 2.7.7/section 2.7.8).
4 Rinse column
Place beaker beneath the column outlet.
Set flow rate for new separating column.
Switch on high-pressure pump and rinse column with eluent
for ca. 10 min, then switch off pump.
5 Connect column to detector block
Screw outlet end of separating column 81 to inlet capillary 45
or suppressor inlet capillary 96.
