The 819 IC Detector is the top-class conductivity
detector. It has been developed specially
for ion chromatography with and without
chemical suppression. The Advanced IC Detector
is especially strong in cation analysis.
It is able to reliably determine even very
small signals against a very high background
conductivity - up to 10 000 µS/cm.
The 819 IC Detector is an integral part
of the modular Advanced Metrohm IC systems.
The wet chemistry part and the electronics
are strictly separated.
The detector block with built-in measuring
cell is thermally and electrically shielded
against outside influences. All signal lines
- including those to the A/D converter - are
specially shielded. A Faraday cage reliably
prevents interference by electrosmog. The measuring
cell is thermostatted and is characterized
by its temperature stability of < 0.01 °C.
The temperature of the detector block can be
set between 25 °C and 45 °C.
Together with electronic preamplification in
the detector block, the 819 IC Detector offers
the highest degree of sensitivity at an optimal
signal-noise ratio. The measuring cell is made
from stainless steel; all supply lines are
either of PEEK (Version 0110) or stainless
steel (Version 0010).
The electronic part of the detector processes
the signal up to the analog output. Seven measuring
ranges are available. The full-scale range
can be set in 11 steps between 0.05% and 100%
of the measuring range, i.e. from measuring
range/2000 to measuring range/1. In combination
with the auto-zero function noise is reduced
to an absolute minimum (electronic noise < 0.0003%
of the selected measuring range).
The 819 IC Detector is remotely controlled
by the Metrodata IC
Net or IC
Cap software. Application-oriented time
programs and (remote-)control programs for
the whole IC system and further peripheral
devices form integral parts of the 819 IC Detector.
If the detector is to be controlled directly
from a PC without the 830
IC Interface, then the 6.2125.110 Cable
is required for the connection 819 IC Detector
- PC (25/9).
