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
