5 Connect column to suppressor module (Suppressor

connection 1)

Cut inlet capillary 27 (marked with “Eluent”) at suppressor

connection 25 (see Fig. 9) to the required length. Use the

6.2126.080 Capillary cutter available as an option.

without column heating

Screw inlet capillary 27 on to the outlet end of separating

column 53 using a 6.2744.010 compression fitting.

with column heating

Connect capillary 52 at the outlet of the separating column

(see Fig. 20, 819/820 Instructions for Use) to the inlet

capillary 27 using the 6.2744.040 Coupling supplied with the

820 standard equipment.

6 Fix column

without column heating

Insert one or two column holders 59 (6.2027.030, 6.2027.040

or 6.2027.050) in the mounting rails 58 and fasten separating

column in the column holder.

with column heating

Insert column heating according to Fig. 10 (819/820

Instructions for Use) into the Separation Center.

7 Connect suppressor module to detector block

(Suppressor connection 1)

Cut outlet capillary 32 (marked with “Detector”) at suppressor

connection 25 (see Fig. 9) to coupling 71(6.2620.060) to the

required length. Use the 6.2126.080 Capillary cutter available

as an option.

Screw outlet capillary 32 on to coupling 71 by using a

6.2744.010 compression fitting.

Screw inlet capillary 56 of detector block 57 on to the other

end of coupling 71.

8 Attach pump tubing to 833 Liquid Handling Unit

Mount both the 6.1826.050 Pump tubing (white-yellow

stopper) as described in Section 3.2, see Fig. 7.

9 Suppressor connection 2: H

Pull inlet capillary 28 (marked with “H

2

SO

4

”) at suppressor

connection 25 (see Fig. 9) through one of the openings 18 on

the rear panel of the 820 IC Separation Center.

Attach inlet capillary 28 (23 in Fig. 7) to the 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.
