Metrohm 838 Advanced Sample Processor, Installation 47
3.5.8 MIC-3 modular anionic and cationic system with chemical suppres-
sion
This system requires the model 2.838.0010 of the 838 Advanced
Sample Processor.
The combined anionic/cationic IC system can operate either with
chemical suppression or with electronic suppression. The 838 Ad-
vanced Sample Processor is connected to the System MIC-3 with two
819 IC detectors, 820 IC Separation Centre (2 injectors), two 818 IC
pumps, 833 IC Suppressor Module and 830 IC Interface in accordance
with Figure 36 using the 6.2125.120 remote adapter, the 6.2125.090
remote cable and the 6.2134.100 RS232 cable.
