3.5 Connection to Metrohm IC systems
46 Metrohm 838 Advanced Sample Processor, Installation
3.5.7 MIC-2 modular anionic system with chemical suppression and ul-
trafiltration of the samples
This system requires the model 2.838.0210 of the 838 Advanced
Sample Processor. Install the ultrafiltration cell, see Chapter 3.3.6.
The 838 Advanced Sample Processor is connected to an anionic IC
system with chemical suppression with 819 IC detector, 820 IC Separa-
tion Centre, 818 IC pump, 833 IC Liquid Handling Unit and 830 IC Inter-
face in accordance with Figure 35 using the 6.2141.190.remote cable
and the 6.2134.100 RS232 cable.
