It may be necessary to clean the MSM in the following cases:
￭ Increased backpressure onto the output capillaries of the MSM.
￭ Blockage of the MSM which cannot be eliminated (solutions can no
longer be pumped through the MSM).
￭ Jamming of the MSM which cannot be eliminated (MSM can no longer
be switched over).

Cleaning the MSM
Clean the MSM as follows:
1 Disconnecting the MSM from the IC system
￭ Switch off the instrument.
￭ Disconnect the MSM from the separation column, peristaltic
pump and detector.
2 Dismantling the MSM
￭ Unscrew union nut (54-1) from the MSM housing (54-4).
￭ Pull MSM connecting piece (54-2) and MSM rotor A (54-3) out of
the MSM housing (54-4). The MSM connecting piece and MSM
rotor A normally stick to one another - if this is not the case: Take
a sharp object, insert into the slot (54-5) in the MSM housing,
and pull out MSM rotor A (54-3) in this way.
