3 Connecting the eluent path
￭
Lead the eluent aspiration tubing (6.1834.080) out of the instru-
ment through a capillary feed-through and connect it with the
eluent bottle (see Chapter 3.8.1, page 25).
￭
Connect the column inlet capillary (6.1831.150) and the capillary
of the MSM labeled with in to one another using a coupling
(6.2744.040) and two short pressure screws (6.2744.070).
￭
Connect the detector inlet capillary and the capillary of the MSM
labeled with out to one another using a coupling (6.2744.040)
and two short pressure screws (6.2744.070).
4 Connecting the sample path
￭
Guide the sample aspiration capillary connected to the sample
input of the injection valve out of the instrument through a capil-
lary feed-through and connect it with the Sample Processor, if
applicable (see Sample Processor manual).
￭
Guide the sample outlet capillary connected to the sample output
of the injection valve out of the instrument through a capillary
feed-through and onward to the waste container and then fasten
it there.
5 Installing the peristaltic pump
Prepare the pump tubing for the regeneration solution:
￭
Plug a tubing olive (6.2744.034) into one end of the pump tubing
(6.1826.320).
Plug a pump tubing connection (6.2744.180) onto the other end
of the pump tubing.
￭
Connect one end of the aspirating capillary (6.1803.020) for the
regeneration solution to the tubing olive on the pump tubing
using a short pressure screw (6.2744.070).
Guide the other end of the aspirating capillary out of the instru-
ment through a capillary feed-through, slide it through a bottle
attachment (6.1602.150) and screw the bottle attachment onto
the bottle (6.1608.020) containing the regeneration solution.
Ensure that the end of the aspirating capillary reaches down to
the bottom of the bottle.
￭
Place the pump tubing into a tubing cartridge.
Prepare a second pump tubing for the rinsing solution:
