Cleaning the MSM-HC
Clean the MSM-HC as follows:
1 Disconnecting the MSM-HC from the IC system
￭ Switch off the instrument.
￭ Disconnect the MSM-HC from the separation column, peristaltic
pump and detector.
2 Dismantling the MSM-HC
￭ Unscrew union nut (47-1) from the MSM-HC housing (47-4).
￭ Pull the MSM-HC connecting piece (47-2) and the MSM-HC rotor
A (47-3) out of the MSM-HC housing (47-4). The connecting
piece and the MSM-HC rotor A normally stick to one another – if
this is not the case: Take a sharp object, insert into the slot (47-5)
in the MSM-HC housing, and pull out the MSM-HC rotor A (47-3)
in this way.
￭ Detach the MSM-HC connecting piece (47-2) from MSM-HC rotor
A (47-3).
3 Cleaning the supply and discharge lines
￭ Connect in turn each of the 6 capillary tubings fastened on the
MSM-HC connecting piece (47-2) on the high pressure pump (see
Chapter 3.10, page 37) and pump through ultra pure water.
