The instrument is now ready for the installation of the columns.

4.2

Conditioning

After the installation and after switching on the instrument, the system
must be conditioned with eluent until a stable baseline is reached.

Note

After a change of eluent (see Chapter 5.4.2.3, page 53), the condi-
tioning time can lengthen considerably.

Conditioning the system

1 Preparing the software

Caution

Ensure that the flow set is not higher than the flow permissible for
the corresponding column (see column leaflet and chip data set).

Start the PC program MagIC Net™.

Open the Equilibration tab in MagIC Net™.

Select (or create) a suitable method.

2 Preparing the instrument

Ensure that the column is correctly mounted according to 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.
