Improvements in amperometric detector for ion chromatography

The ion chromatography is presented as an excellent tool for analysis of inorganic anions and cations, amines, organic acids, amino acids and carbohydrates. The amperometric, conductometric and spectrophotometric detectors are the most used in this type of instrumentation. The amperometric detector is used mainly when the analytes have low relative conductivity and no chromophores groups, as example, cyanides, sulfides and  biomolecules such as carbohydrates and amino acids. Currently the need to minimize losses in industrial processes and developments related to the conversion of biomass increased the need for improvements in amperometric detectors such as reduce the need for maintenance, increase the detectability and repeatability of measurements. So the goal of this line is to design and build more efficient flow cells, develop new pulsed modes of detection, study and application of new electrocatalytic materials.
