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

See Chapter 3.10, Page 34

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.
