Amperometric detector improves selectivity and measurement sensitivity

A new Amperometric detector has been added to Metrohm's chromatography systems, which improves selectivity and offers enhanced measurement sensitivity.

The detector, which features intelligent and maintenance-free optimized measuring cells, can be used as an alternative to conductivity and UV/VIS detectors when determining electroactive components.

The amperometric detection is described by the company as far more "robust" and easier to use than ever before, exhibiting strikingly low noise and excellent signal strength as a consequence of the three electrode design in the wall-jet or thin-layer geometry.

Metrohm's detector is also considered to be significantly more flexible. Depending on the application, the direct current mode, the pulsed amperometric detection mode, the highly flexible integrated pulsed amperometric mode, or the cyclovoltammetric mode may all be used.

It is available as both an inlay detector (850 IC Amperometric Detector) or as a stand-alone detector (896 Professional Detector), both of which can be used with either an 850 Professional IC, with an 881 Compact IC pro, or with an 882 Compact IC plus.

They can be also be operated in series or parallel to other analytical channels, depending on the task at hand.

Metrohm is a global manufacturer of precision instruments for chemical analysis.
