5 Mount pump tubing on the 833 Liquid Handling Unit
• Mount the two lengths of 6.1826.010 Pump tubing (white-
white stopper) as described in Section 3.2, see Fig. 7.
6 Sample preparation module connection 2:
Regenerant
• Pull inlet capillary 37 (marked with “Regenerant”) at sample
preparation module connection 34 (see Fig. 13) through one
of the openings 18 on the rear panel of the 820 IC Separation
Center.
• Attach inlet capillary 37 (23 in Fig. 7) to filter unit PEEK 22
(6.2821.120) of the first pump tubing using a compression
fitting 17 (6.2744.010), see Fig. 7.
• Mount aspiration tubing: cut a piece of PTFE tubing 16
(6.1803.020) to the required length.
• Attach a PEEK compression fitting 17 (6.2744.010) to one
end of the PTFE tubing 16 and screw this on to coupling 18,
see Fig. 7.
• Immerse the other end of the aspiration tubing in a container
with regeneration solution (normally 20 mmol/L perchloric
acid) and fix it in position.
• Pull outlet capillary 38 (marked with “Waste”) at sample
preparation module though one of the openings 18 of the
rear panel of the 820 IC Separation Center.
• Lead outlet capillary 38 into a sufficiently large waste bottle
and fix it in position.
7 Sample preparation module connection 3: H2O
• Pull inlet capillary 40 (marked with “H
2
O”) at Sample
preparation module connection 34 (see Fig. 13) through one
of the openings 18 on the rear panel of the 820 IC Separation
Center.
• Attach inlet capillary 40 (23 in Fig. 7) to the filter unit PEEK 22
(6.2821.120) of the second pump tubing using a PEEK
compression fitting 17 (6.2744.010), see Fig. 7.
• Mount aspiration tubing: cut a piece of PTFE tubing 16
(6.1803.020) to the required length.
• Attach a PEEK compression fitting 17 (6.2744.010) to one
end of the PTFE tubing 16 and screw this on to coupling 18,
see Fig. 7.
• Immerse the other end of the aspiration tubing in a container
with rinsing solution (normally deionized water) and fix it
position.
• Pull outlet capillary 39 (marked with “Waste”) at Sample
preparation module connection 34 (see Fig. 13) through one
of the openings 18 in the rear panel of the 820 IC Separation
Center.
• Lead outlet capillary 39 into a sufficiently large waste bottle
and fix it in position.
