844 UV/VIS Compact IC844 UV/VIS Compact IC – first of its kindWith the 844 UV/VIS Compact IC, Metrohm presents the first compact ion chromatographwith UV/VIS detection worldwide. This instrument impresses with thefollowing features:• Favorable purchase price and low operating costs• Easy and powerful system control with IC Net or IC Cap software• Small footprint means very small space requirements• High precision• Low detection limits• PEEK flow path – fully solvent-compatible• High-quality system and components made in SwitzerlandExtremely compact design combined with leading technologyand very easy operation: the new 844 UV/VISCompact IC.Leading technology• Diode-array detector (DAD)• Three wavelengths plus freely selectable reference wavelength• Peak-ratio channel• Variable bandwidths for detection wavelength (peak bunching)• Scan mode for spectra recording and simple system optimization• Combined UV and VIS lamp system• No lamp change• Integral post-column reactor (PCR)• Column heating for two separation columnsInstrumentThe 844 UV/VIS Compact separates and determines substances that absorb in theultraviolet or visible part of the spectrum. The introduction of this system opens awide range of applications that are not directly accessible to ion chromatographywith conductivity detection.Some important application fields are:• Detection of heavy metals• Wastewater containing chromium in leather production• Corrosion checks in power plants• Determination of bromate in drinking water• Determination of sulfur compounds in wastewater• Measurement of nitrite and nitrate in seawaterMetrohm Information Issue 2/2005 7
