4 Connect SP Module A to valve A
x Screw outlet capillary 29
29 29 29 marked with “Sample out” onto
connection “1” of injection valve A using a 6.2744.010
compression fitting.
5 Attach pump tubings
x Loosen both tubing cartridges 4
444 from the holding clamp 9999 by
pressing down snap-action lever 10 10 10 10 and remove from
mounting pin 12 12 12 12 on 793 Sample Prep Module (see Fig. 1).
x Press contact pressure lever 5 555 on both tubing cartridges
down as far as it will go.
x Insert a length of pump tubing 33 33 33 33 (6.1826.010, ~1.3 mL/min)
into each of the tubing cartridges as shown in Fig. 7. The
white-white stopper 34 34 34 34 must click into the corresponding
holder on the left-hand side of the tubing cartridge.
x Place the tubing cartridges on mounting pin 12 12 12 12 and press
down on the right-hand side until snap-action lever 10 10 10 10 clicks
into position on holding clamp 9999. Take care that no kinks are
formed in the pump tubing.
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.
