1 Introduction
1.1 Instrument description
The 753 Suppressor Module consists of a suppressor block with its
corresponding control unit; this contains an additional 2-channel peri-
staltic pump.
Ion chromatographic analyses with chemical suppression can be car-
ried out with the suppressor built into the suppressor block. The sup-
pressor consists of a total of 3 suppressor units which are in turn used
for suppression, regenerated with sulfuric acid and rinsed with water. In
order to record each new chromatogram under comparable conditions
a freshly regenerated suppressor unit is normally used. Switching is ei-
ther carried out automatically together with valve switching or manually.
At the control unit the suppressor can either be switched to the next
position manually or by remote control via the remote interface. The
built-in peristaltic pump, which delivers the solutions required for oper-
ating the suppressor, can also be switched on by remote control or
manually.
The 753 Suppressor Module is particularly suitable for retrofitting the
690 Ion Chromatograph for chemical suppression in a simple manner.
This application is described in detail in these instructions for use.
The 753 Suppressor Module can also be used together with the 732 IC
Detector and the 733 IC Separation Center (e.g. for the realization of a
complete two-channel IC system with only one 733 Separation Center).
Of course the 753 Suppressor Module can also be combined with all
other HPLC components currently on the market.
