To avoid contamination of the suppressor module by foreign particles
or bacterial growth, it is advantageous to install an in-line filter be-
tween the 833 IC Liquid Handling Pump Unit and the suppressor mod-
ule. For this the two 6.2821.120 Filter units PEEK (mounting see Fig.
18 Section 2.7.3) supplied with the 2.833.0010 IC Liquid Handling
Pump Unit should be used.
The suppressor module must never be switched in the dry state as
there is a danger of blocking. Before every switching operation of the
suppressor module, the three suppressor units must have been
rinsed for at least ½ h with eluent, regeneration and rinsing solution.
