7 Rinse dialysis system
• At the end of the measurements immerse sample aspiration
tubing 16 in the acceptor solution.
• Start the peristaltic pumps in «IC Net» by setting the remote
line 1 (833 Pump Unit) and remote line 2 (833 Dialysis Unit) in
the window of the 819 Detector.
• Rinse the dialysis system with acceptor solution for approx.
10 min and then switch off the pump again.
8 Closing down the dialysis system
• To shut down the dialysis cell the acceptor and sample
channels must be rinsed with ultrapure water for approx. 10
min. The inlet and outlet tubing is then screwed off from the
dialysis cell and openings 49, 50, 51 and 52 (see Fig. 15) are
each closed with a 6.2744.060 Blank stopper.
• If the dialysis system is not to be used for a long time then the
dialysis membrane must be removed and the cell has to be
cleaned, see Section 9.2.7.1 and Fig. 15.
