2.8.3 Connection of supply bottles
The supply lines for the regeneration and rinsing solution between the
storage bottles and the peristaltic pump are installed as follows (see
Fig. 17):
1 Prepare supply bottle for H

• Prepare regeneration solution suited for the desired applica-
tion and separating column (normally 20 mmol/L H

).
• Fill regeneration solution into supply bottle 103 (amber glass,
1 L) and label the bottle.
• Screw bottle attachment 102 on to supply bottle 103.
• Place supply bottle 103 at one of the rear positions of the
bottle rack 10 on the 761 Compact IC (see Fig. 1).
2 Connect aspirating tubing for H

• Prepare aspirating tubing 90: Cut a piece of the 6.1803.020
PTFE tubing to the required length (normally ca. 120 cm).
• Pull one end of aspirating tubing 90 through a PEEK com-
pression fitting 54 (6.2744.010) so that approx. 30 cm of the
tubing projects.
• Screw PEEK compression fitting 54 with tubing into one
opening of bottle attachment 102 attached to the regenera-
tion solution storage bottle and tighten it so that the tubing is
firmly held.
• Insert the free end of aspirating tubing 90 into one of the
openings in 12 of the 761 Compact IC (see Fig. 2) from
above and pull it sufficiently far into the interior.
• Mount a coupling 91 (6.2744.030) to the inlet end of the rear
