Wayeal IC6200 Foods and Beverages Use Ion Chromatography With Conductivity Detector
Introduction of Ion Chromatography Instrument
Ion chromatography, a form of liquid chromatography, measures concentrations of ionic species by separating them based on their interaction with a chromatographic column stationary phase. Ionic species separate differently, depending on species type and size. Sample solutions pass through a pressurized chromatographic column where ions are retained by column constituents due to ionic interactions. As an ion extraction liquid, known as eluent, runs through the column, the retained ions begin separating from the column and eventually reach the detector where it produces a change in the signal which is represented by a peak in the chromatogram. Ions of interest can be identified, based on their retention time and quantitated, based on the detector’s response and standards to those ions.
