5 Connect suppressor module to detector block
(Suppressor connection 1)
• Cut outlet capillary 69 (marked with “Detector”) of suppressor
module 70 to the required length. Use the 6.2126.080
Capillary cutter available as an option.
• Screw outlet capillary 69 on to coupling 71 by using a
6.2744.010 Pressure screw.
• Screw inlet capillary 56 of detector block 57 on to the other
end of coupling 71.
6 Mount pump tubing on 833 Pump Unit
• Mount the two lengths of 6.1826.050 Pump tubing (white-
yellow stopper) with aspirating tube 16 and filter unit PEEK
22 6.2821.120 as described in Section 3.2, see Fig. 7.

") by hand as far as
required through one of the feedthroughs 14 to the outside
(see Fig. 23 and Fig.24, 819/820 Instructions for Use).
• Screw the filter unit PEEK contained in the standard
equipment of the 833 IC LH Pump Unit on to PEEK coupling
21 (6.2744.160) as described in Section 3.2 at the outlet end
of the first piece of pump tubing 19.
• Fasten inlet capillary 65 (23 in Fig. 7) to filter unit PEEK
(6.2821.120) by using a compression fitting 17 (6.2744.010)
(see Fig. 7).
• At the inlet end of the first piece of tubing 19 fasten a suitably
long piece of PTFE tubing 16 (6.1803.020) to coupling 18
(6.2744.034) by using a compression fitting 17 (6.2744.010).
• Immerse the other end of the aspiration tubing in a container
with regeneration solution (normally 50 mmol/L H

) and fix
it in position.
• Pull outlet capillary 66 of the suppressor module (marked
with "Waste") through opening 18 on the rear panel, lead it
into a sufficiently large waste bottle and fix it in position.

") by hand as far as
required through one of the feedthroughs 14 to the outside
(see Fig. 23 and Fig.24, 819/820 Instructions for Use).
• Screw the filter unit PEEK contained in the standard
equipment of the 83 IC LH Pump Unit on to PEEK coupling
21 (6.2744.160) as described in Section 3.2 at the outlet end
of the second piece of pump tubing 19.
• Fasten inlet capillary 68 (23 in Fig. 7) to the filter unit PEEK
(6.2821.120) by using a compression fitting 17 (6.2744.010)
(see Fig. 7).
