2 Preparing the instrument
￭ Ensure that the column is correctly mounted in accordance with
the flow direction indicated on the label (arrow must point in the
direction of flow).
￭ Ensure that the eluent aspiration tubing is immersed in the eluent
and that there is enough eluent in the eluent bottle.
3 Checking leak-tightness
￭ In MagIC Net, start the equilibration.
￭ Check all capillaries and their connections from the high pressure
pump to the detector block for signs of liquid escaping. If eluent
escapes anywhere, tighten the corresponding pressure screw or
loosen the connection, check the end of the capillary, shorten it
with a capillary cutter if necessary, and restore the connection.
4 Conditioning the system
Rinse the system with eluent until the required stability of the base-
line is attained (normally 30 minutes).
The instrument is now ready for measuring samples.
