2.4.2 Connection to eluent container
The 6.1834.000 Aspirating tubing (i.d. = 1.5 mm, o.d. = 2.5 mm,
length = 1.2 m) supplied is slid over the aspirating capillary 7. The
6.2821.090 Aspirating filter supplied is screwed onto the other end of
the tubing. The end of the tubing with the aspirating filter is then
introduced in the eluent container.
Only degassed (with N
2
, He or vacuum) and microfiltered (0.45 µ m
filter) eluents may be used!
It must be ensured that the eluent used is freely miscible with any
residual solvent in the pump head (the pump head is filled with
isopropanol or methanol/water in the factory). If this is not the case,
the pump must first be rinsed with a solvent that is miscible with both
the previous and subsequent eluent (e.g. acetone).
If you use the optional available 6.5324.000 Bottle rack, the
6.1834.010 Aspirating tubing (accessory of the bottle rack, length =
2.5 m) must be installed instead of the 6.1834.000 Aspirating tubing.
The end of the tubing with the screwed-on 6.2821.090 aspirating filter
is then fixed in the eluent vessel according to the instructions on the
leaflet supplied with the bottle rack.
