850 Professional IC Anion – MSM-HC – MCS – Prep 3
5.13 High Capacity Metrohm Suppressor Module
(MSM-HC)
5.13.1 Protection
To protect the MSM-HC against foreign particles or bacterial growth, a
6.2744.180 pump tubing connection with filter (see Figure 32, page 54)
must be mounted between the peristaltic pump and the inlet capillaries of
the MSM-HC .
5.13.2 Operation
Note
The suppressor units must never be regenerated in the same flow direc-
tion in which the eluent is pumped. Therefore always mount the inlet
and outlet capillaries according to diagram outlined in figure 37.
The MSM-HC consists of 3 suppressor units, which are used for suppres-
sion, regenerated with sulfuric acid or rinsed with ultra pure water in rota-
tion. In order to record every new chromatogram under comparable con-
ditions, you should normally work with a freshly regenerated suppressor.
Caution
The MSM-HC must never be switched over in a dry state, as there is a
risk of jamming. If the MSM-HC is in a dry state, the MSM-HC must be
rinsed for at least 5 minutes before it may be switched over.
Caution
In the case of reduced capacity or high backpressure, the MSM-HC
must be regenerated (see Chapter 5.13.3.1, page 107), cleaned (see
Chapter 5.13.3.2, page 108) or replaced (see Chapter 5.13.3.3, page
110).
