suppressor drive if the rotor is inserted correctly.
If this is not the case, then the rotor must be moved into the cor-

removed, it can be moved into the correct position from below by
means of a pointed object (e.g. a screwdriver).

Replacing parts of the Metrohm Suppressor
Module (MSM)
Parts of the Metrohm Suppressor Module (MSM) may need to be replaced
in the following cases:
￭
Irremediable loss of suppressor capacity (reduced phosphate sensitivity
and/or significant rise in the baseline).

Irremediable blockage of the MSM (solutions can no longer be pum-
ped through the MSM).
Both the rotor and the connecting piece can be replaced.
