Metrohm complements its portfolio of intelligent ion
chromatography systems with an amperometric detector. As an alternative
to conductivity and UV/VIS detectors it can always be used when
electroactive (i.e. oxidizable or reducible) components are to be
determined. The new amperometric detector excels by its high selectivity
and measurement sensitivity. It can be used for sensitive and accurate
determination of concentrations down to the ng/L-range.
The new amperometric detector features optimized measuring cells that
are intelligent, maintenance-free, and easy to use. As a consequence of
their three electrode design in the wall-jet or thin-layer geometry,
they exhibit strikingly low noise and excellent signal strength. A
variety of 2 mm and 3 mm electrodes in the usual materials of gold,
silver, platinum, and glassy carbon are available for a wide variety of
applications. The maintenance-free auxiliary and reference electrodes
complement your detection system. This makes amperometric detection more
robust and easier to use than ever before.
Depending on the
application, the direct current mode (DC), the pulsed amperometric
detection mode (PAD), the highly flexible integrated pulsed amperometric
mode (flexIPAD), or the cyclovoltammetric mode (CV) may be used. The
flexibility of the detector also includes the selection of the measuring
signal: whether current or charge, users always benefit from reliable
results.
Metrohm offers the amperometric detector in the form of
an inlay detector (850 IC Amperometric Detector) or as a stand-alone
detector (896 Professional Detector). Both instruments can either be
used with an 850 Professional IC, with an 881 Compact IC pro, or with an
882 Compact IC plus. Depending on the task, they can be operated in
series or parallel to other analytical channels. The ion chromatography
software MagIC Net
TM is used for control, data recording, and data
evaluation.
