• Pull the inlet capillary 2828 marked with “H
2
O“ at suppressor
connection 2222 (see Fig. 6) through one of the rear panel
openings 2929 of the 690 Ion Chromatograph or through the
door gap in the right-hand lower corner of the interior door
1313.
• 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.
