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
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.

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.
