1.1.2 833 IC Liquid Handling Suppressor Unit
As well as the basic instrument, the 833 IC Liquid Handling
Suppressor Unit includes a suppressor module connected to the
basic instrument and also remotely controlled by IC Net.
With the suppressor included in the suppressor module analyses by
ion chromatography with chemical suppression can be carried out. The
suppressor consists of a total of 3 suppressor units which are used in
rotation for suppression, regeneration with sulfuric acid and rinsing with
water. In order that each new chromatogram is recorded under
comparable conditions a freshly regenerated suppressor unit is
normally used. Switching takes place automatically.
The 833 IC Liquid Handling Suppressor Unit is particularly suitable
for retrofitting existing IC systems for chemical suppression in a simple
way. For example, this means that the 833 IC Liquid Handling
Suppressor Unit can be used together with two 819 IC Detectors, two
818 IC Pumps and an 820 IC Separation Center without suppressor
(2.820.0220) to realize a complete 2-channel IC system with only a
single Separation Center.
