￭
Connect the leak sensor (see "Connecting the leak sensor ", page
22).
￭
Connect drainage tubings (see "Installing drainage tubings",
page 25).
3 Installing the eluent path
￭
Equip the eluent aspiration tubing and connect with the eluent
bottle (see Chapter 3.8.1, page 28).
￭
Instead of the column, connect the 6.2744.040 coupling with a
6.2744.070 short pressure screw at the end of the pre-installed
column inlet capillary.
￭
Connect the detector inlet capillary with a 6.2744.070 short pres-
sure screw to the 6.2744.040 coupling.
4 Installing the sample path
Note
The sample degasser does not have to be connected. We recom-
mend the usage of the sample degasser only if the sample matrix
requires it.
￭
Guide the 6.1803.040 sample aspiration capillary connected to
the sample input of the injection valve out of the instrument
through a capillary feed-through and connect it with the Sample
Processor or
￭
If the sample degasser is used: Connect the sample aspiration
capillary with a 6.2744.090 long pressure screw to the output of
the sample degasser (see Chapter 3.14, page 44).
Connect a part of the 6.1803.040 sample aspirating capillary with
a 6.2744.090 long pressure screw to the input of the sample
degasser. Guide the other end out of the instrument through a
capillary feed-through and connect it to the Sample Processor (see
Sample Processor manual).
5 Expanding the instrument to low pressure gradient
￭
Loosen the 6.1834.090 connection tubing (1-5) from the output
of the eluent degasser.
￭
Dismount the coupling (20-9) and pump head inlet capillary
(20-7) of the high pressure pump.
