Suppressor connection 3: H

O
• Pull the inlet capillary 2828 marked with “H
2
O“ at suppressor
connection 2222 (see Fig. 6) through one of the rear panel
openings 4141 or 4343 of the 733 IC Separation Center.
• Mount a PEEK compression fitting 3131 (6.2744.010) on the
end of inlet capillary 2828 and screw this on to coupling 3232
(6.2744.030) (see Fig. 7).
• Push coupling 3232 on to the outlet end of the second pump
tubing 3333 (see Fig. 7).
• Mount suction tubing: cut a piece of PTFE Tubing 3030
(6.1803.020) to the desired length.
• Mount a PEEK compression fitting 3131 (6.2744.010) on one
end of PTFE tubing 3030 and screw this on to coupling 3232 (see
Fig. 7).
• Push coupling 3232 on to the inlet end of the second pump
tubing 3333 (see Fig. 7).
• Immerse the other end of the suction tubing in a vessel
containing rinsing solution (normally dist. H
2
O) and fix in
place.
• Pull outlet capillary 2727 marked with “Waste“ at suppressor
connection 2222 (see Fig. 6) through one of the rear panel
openings 4141 or 4343 of the IC Separation Center 733.
• Lead outlet capillary 2727 to a sufficiently large waste container
and fix in place.

Startup of 753 Suppressor Module
• Set switch <REMOTE> 22 to "OFF".
• Switch on 753 Suppressor Module with mains switch 1313 and
set switch <PUMP> 33 to "ON".
• Adjust the contact pressure for both tubing cartridges: press
contact pressure lever 55 upwards until the solutions just start
to be drawn in. Then press the contact pressure lever up-
wards until it clicks once more to obtain optimal contact pres-
sure.
• Before switching the suppressor to the next position for the
first time rinse all three suppressor units with solution for
5 min.
• Check all tubing from the storage vessels through the tubing
cartridges and the suppressor up to the waste containers for
leakage of liquids. If liquid escapes anywhere the corre-
sponding compression fitting must be tightened further or
changed.
Pump tubings are consumable material with a lifetime which depends
on the contact pressure. This is why the tubing cartridges should be
raised completely by loosening snap-action lever 1010 on the right-hand
side if the pump is to remain switched off for a considerable length of
time (the set contact pressure remains unchanged).
