Connect the PTFE capillaries firmly mounted on the connecting piece to
the other components of the IC system as follows:
Connecting the capillaries of the suppressor
In order to protect the Suppressor from foreign particles or bacterial
growth, the following precondition must be fulfilled:
￭ Pump tubing connections with filter (6.2744.180) are installed at the
pump tubing outlets of the peristaltic pump.
Caution
As the PTFE capillaries are very soft, the pressure screws should not be
overtightened.
Squeezed capillary ends can be shortened with the capillary cutter
(6.2621.080).
1 Connecting the eluent inlet capillary
￭ Fasten the end of the inlet capillary labeled with in to the output
of the column with a short PEEK pressure screw (6.2744.070).
2 Connecting the eluent outlet capillary
Note
Depending on the instrument type, the suppressor is either con-
nected directly with the detector or, if available and used, with the
MCS.
￭ Connect the output capillary labeled with out either with the
detector (see manual of the detector).
or
￭ Connect the output capillary labeled with out with the input in of
the MCS, using a long PEEK pressure screw (6.2744.090).
3 Connecting the rinsing solution inlet capillary
￭ With a short PEEK pressure screw (6.2744.070), fasten the end of
the inlet capillary labeled with rinsing solution to the pump tub-
ing connection of the pump tubing which carries the rinsing solu-
tion.
