Replacing the suppressor
The suppressor in the suppressor block may have to be replaced in the
following cases:
x Irremediable loss of suppressor capacity (reduced
phosphate sensitivity and/or strong rise in baseline)
x Irremediable blockage of the suppressor (the suppres-
sor can no longer deliver solutions)
Both the 6.2832.000 Suppressor rotor and the 6.2832.010 Connection
piece with the input and output leads can be replaced. To replace these
components proceed as follows (see Fig. 19):
1 Disconnect suppressor from IC system
x Disconnect all input and output leads of the suppressor from
IC system and peristaltic pump.
2 Dismantle suppressor
x Unscrew nut 102
