Replacing Capillaries On A Semi-Micro, Micro And High Pressure Flow Cell - Agilent Technologies G1315B User Manual

Replacing Capillaries on a Semi-Micro, Micro and High Pressure
Flow Cell
When required
Tools required
Parts required
Preparations
All descriptions in this procedure are based on the default orientation of the cell (as it is
N O T E
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).
The fittings at the flow cell body are special types for low dead volumes and not compatible
N O T E
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.
