6 SP Module A connection 2: Regenerant
x Pull the inlet capillary 25
25 25 25 marked with “Regenerant“ at SP
Module A connection 22 22 22 22 (see Fig. 6) through one of the rear
panel openings 41 41 41 41 or 43 43 43 43 of the 733 IC Separation Center.
x Mount a PEEK compression fitting 31 31 31 31 (6.2744.010) on the
end of inlet capillary and screw this on to PEEK filter unit 36 36 36 36
(6.2821.100) (see Fig. 7).
x Mount coupling 35
35 35 35 on to the inlet of the PEEK filter unit and
push this coupling on to outlet end of the first pump tubing
33 33 33 33 (see Fig. 7).
x Mount suction tubing: cut a piece of PTFE Tubing 30
30 30 30
(6.1803.020) to the desired length.
x Mount a PEEK compression fitting 31
31 31 31 (6.2744.010) on one
end of PTFE tubing 30 30 30 30 and screw this on to coupling 32 32 32 32 (see
Fig. 7).
x Push coupling 32
32 32 32 on to the inlet end of the first pump tubing
33 33 33 33 (see Fig. 7).
x Immerse the other end of the suction tubing in a vessel
containing regeneration solution (normally 20 mmol/L HClO
4
)
and fix in place.
x Pull outlet capillary 26
26 26 26 marked with "Waste" at SP Module A
connection 22 22 22 22 (see Fig. 6) through one of the rear panel
openings 41 41 41 41 or 43 43 43 43 of the 733 IC Separation Center.
x Lead outlet capillary 26 26 26 26 to a sufficiently large waste container
and fix in place.

x Pull the inlet capillary 28
28 28 28 marked with “H
2
O“ at SP Module A
connection 22 22 22 22 (see Fig. 6) through one of the rear panel ope-
nings 41 41 41 41 or 43 43 43 43 of the 733 IC Separation Center.
x Mount a PEEK compression fitting 31
31 31 31 (6.2744.010) on the
end of inlet capillary 28 28 28 28 and screw this on to the second
PEEK filter unit 36 36 36 36 (6.2821.100) (see Fig. 7).
x Mount coupling 35
35 35 35 on to the inlet of the PEEK filter unit and
push this coupling on to outlet end of the second pump tub-
ing 33 33 33 33 (see Fig. 7).
x Mount suction tubing: cut a piece of PTFE Tubing 30 30 30 30
(6.1803.020) to the desired length.
x Mount a PEEK compression fitting 31 31 31 31 (6.2744.010) on one
end of PTFE tubing 30 30 30 30 and screw this on to coupling 32 32 32 32 (see
Fig. 7).
x Push coupling 32
32 32 32 on to the inlet end of the second pump
tubing 33 33 33 33 (see Fig. 7).
x Immerse the other end of the suction tubing in a vessel con-
taining rinsing solution (normally dist. H
2
O) and fix in place.
x Pull outlet capillary 27
27 27 27 marked with “Waste“ at SP Module A
connection 22 22 22 22 (see Fig. 6) through one of the rear panel ope-
nings 41 41 41 41 or 43 43 43 43 of the IC Separation Center 733.
x Lead outlet capillary 27
27 27 27 to a sufficiently large waste container
and fix in place.
