Replacing Capillaries on a Standard Flow Cell
When required If the capillary is blocked
Tools required Two 1/4 inch wrenches for capillary connections
Wrench 4 mm for capillary connections
Screwdriver Pozi 1 PT3
Parts required For parts see
“Standard Flow Cell” on page 146
Preparations Turn the lamp(s) off.
Remove the front cover.
Remove the flow cell, see
“Exchanging a Flow Cell” on page 103.
NOTE
All descriptions in this procedure are based on the default orientation of the cell (as it is
manufactured). The heat exchanger/capillary and the cell body can be fixed mirror
symmetrically to have both capillaries routed to the bottom or to the top (depending on the
routing of the capillaries to the column).
NOTE
The fittings at the flow cell body are special types for low dead volumes and not compatible
with other fittings.
When retightening the fittings, make sure that they are carefully tightened (handtight plus
1/4 turn with a wrench). Otherwise damage of the flow cell body or blockage may result.
