The 844 UV/VIS Compact IC combines all system components in one compact protective housing: injector, high-pressure pump, column heating, post-column reactor, reagent pump and the newly developed array UV/VIS detector. An ordinary PC is all that's needed to run the complete system. The IC Net software enables easy and intuitive operation of the system. The optimized data acquisition allows to evaluate data while the chromatogram is still being recorded. The large selection of Metrosep separation columns guarantees successful analyses.
Conductivity or UV/VIS?
Ion chromatography is a highly efficient tool for assessing the environmental impact of ionic species: Be it nutrients or pollutants, drinking water or wastewater, pharmaceutical products or the impurities they contain – IC assures reliable analytical assessments concerning ionic content.
The aim of ion chromatography is to first separate and then reliably detect ionic substances. As we deal with ions, detection based on conductivity is successful in most cases. If, however, conductivity detection is adversely affected or even rendered impossible by matrix effects or insufficient separation of the analyte ions, use of an alternative detection method can supply essential information.
When conductivity detection does not yield the desired results, the absorption of ultraviolet and visible light by the sample can supply the correct analytical information.
Of course, UV/VIS detection can only be successful if the substances absorb part of the incident light.
