1 Connect column to injector
• Remove end caps from column 53
• without column heating:
Screw inlet end of separating column 53 (note flow direction)
to column connection capillary 50 mounted on the injector.
• with column heating:
Prepare column heating according to Section 2.9.2 and
screw column connection capillary 50 (see Fig. 20) with a
compression fitting to injection valve 51.
• With precolumn:
Install precolumn according to the supplied leaflet between
inlet of the separating column and the injection valve.
2 Rinse column
• Place a beaker beneath the column outlet.
• Start 818 IC Pump in «IC Net» with suitable flow (see leaflet of
the column) and rinse column for ca. 10 min with eluent.
• Stop 818 IC Pump.
