MMS III Suppressor
The MMS III suppressor reduces the eluent conductivity and enhances the
conductivity of the sample ions, thereby increasing detection sensitivity.
As illustrated in Figure 2-5
, a
constant flow of regenerant
over the membrane
continually restores the
suppression ability of the
MMS III.
A process called
Displacement Chemical
Regeneration (DCR) pushes
regenerant from the
regenerant reservoir and
through the suppressor. See
Section 2.2.1
for details.
For more information about
the MMS III, see Installation
Instructions and
Troubleshooting Guide for
the Anion MicroMembrane
Suppressor® III (Document
No. 031727) or Installation
Instructions and
Troubleshooting Guide for
the Cation MicroMembrane
Suppressor® III (Document
No. 031728).

Pressure Transducer
The pressure transducer measures the system pressure at the point that the
eluent flows from the pump head outlet check valve into the pressure
transducer. Pressure measurements, which can be monitored from
Chromeleon, indicate that the pumping system is delivering smooth,
