2.5 System for the analysis of anions and
sugars – MIC-9
The combination of an anion system with chemical suppression with the
IC system for sugar analysis is described as an example of a complete
IC system for the simultaneous determination of anions and sugars.
As ideally the two sample loops for the different separation pathways
should be connected by as short a piece of capillary as possible for
sample injection, a 733 IC Separation Center with two injectors
(2.733.0120) is used. This means that the 812 Valve Unit is no longer
required for sample injection for the Bioscan. The MSM Suppressor
Module, which is frequently located in the 733 IC Separation Center, is
then replaced by the 753 IC Suppressor Module which is used instead
of the 752 IC Pump Unit.
2.5.1 Electrical connections
The electrical connection of the system, consisting for example of two
709 IC Pumps, 817 Bioscan, 732 IC Detector, 733 IC Separation Center
(2 injectors), 753 IC Suppressor Module, 762 IC Interface and 766 IC
Sample Processor is made according to the Figure 9:
