30 Metrohm 838 Advanced Sample Processor, Installation
Proceed as follows in order to connect the dialysis cell 37 to the IC sys-
tem:
Capillaries provided with new connectors must feature a flawless, flat
cut edge. In order to ensure this, it is best to use the 6.2621.080
cappillary cutter..
Connections for sample solution
1 Fitting the pump tubing to the 838 Advanced Sam-
ple Processor
Fit the two 6.1826.040 pump tubings (black-black stop-
pers), as described in Chapter 3.3.8, to the peristaltic pump
of the 838 Advanced Sample Processor.
2 Connecting the aspiratory capillary for sample
Attach one end of the 6.1803.040 aspiratory capillary 68 (L
=1 m) with a 6.2744.010 PEEK pressure screw to the PEEK
coupling on the aspiration end of the black-black pump tub-
ing of channel 1 of the 838 Advanced Sample Processor
(see Chapter 3.3.12 and Figure 22).
Connect the other end of the aspiratory capillary 68 to the
PEEK needle 22 (see Chapter 3.3.4 and Figure 14) and fix the
capillary in position in the guide chain of the 838 Advanced
Sample Processor.
3 Connecting the dialysis cell
Attach the 6.1803.040 PTFE capillary 72 (L =1 m) with a
6.2744.010 PEEK pressure screw to the 6.2744.034 PEEK
coupling on the delivery end of the black-black pump tubing
of channel 1 of the peristaltic pump of the 838 Advanced
Sample Processor (see Chapter 3.3.12 and Figure 22).
Guide the other end of the capillary through one of the open-
ings at the front or on the side of the 820 Separation Centre
into the column chamber and screw it on to the inlet opening
46 of the cell lower section 41 of the dialysis cell using a
6.2744.000 PVDF pressure screw 64 (see Chapter 3.3.7 and
Figure 18).
Screw the 6.1803.040 PTFE capillary 73 (L =1 m) with a
6.2744.000 PVDF pressure screw 64 to the outlet opening 47
of the cell lower section 41 of the dialysis cell (see Chapter
3.3.7 and Figure 18) and guide it through one of the openings
at the front or at the side of the 820 Separation Centre out of
the column chamber. Attach the other end of the PTFE capil-
lary 73 with a 6.2744.010 PEEK pressure screw 64 to the
PEEK coupling at the aspiration end of the black-black
pump tubing of channel 2 of the peristaltic pump of the 838
Advanced Sample Processor (see Chapter 3.3.12 and
Figure 22).
