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 (46-1) from the MSM housing (46-4).
￭ Pull MSM connecting piece (46-2) and MSM rotor A (46-3) out of
the MSM housing (46-4). 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 (46-5) in the MSM housing,
and pull out MSM rotor A (46-3) in this way.
￭ Detach the MSM connecting piece (46-2) from MSM rotor A
(46-3).
3 Cleaning the supply and discharge lines
￭ Connect in turn each of the 6 capillary tubings fastened on the
MSM connecting piece (46-2) on the high pressure pump (see
Chapter 2.10, page 31) and pump through ultra pure water.
