1.1.3 Schematic arrangement of the IC systems
The 819 IC Detector and 820 IC Separation Center are the main com-
ponents of a modular ion chromatography system that can be ex-
panded to meet the wishes of the individual user (see Fig. 1). The
minimum configuration of the one-channel system also includes a 818
IC Pump, a separating column, a 830 IC Interface and an PC. The two-
channel system requires at least a second 819 IC Detector and a sec-
ond 818 IC Pump. Both systems can be extended virtually without any
limits by further modular Metrohm IC devices such as sample changers
for automation, sample preparation devices, components for post-
column derivation and other detectors. Further, practically all HPLC pe-
ripherals and parts available on the market such as precolumns, addi-
tional separating columns, additional detectors and other injection sys-
tems can be seamlessly integrated in the system.
However, the individual IC units can also be freely combined with
common HPLC instruments. This offers the possibility of expanding
your system to a stand-alone ion chromatograph.
