Discovering ways to better judge water quality is an important mission for scientists across the globe. Purnendu 鈥淪andy鈥� Dasgupta believes he may have discovered a device to do just that. The Jenkins Garrett Professor of Chemistry and Biochemistry and his research group invented a charge detector for ion chromatography, a device that can improve water quality testing and manufacturing methods. The components that make up organic and inorganic compounds in water carry differing levels of charged ions. Dr. Dasgupta鈥檚 patented method uses a membrane-based separation or desalting technology that detects ions in proportion to their charge and concentration. 鈥淲ater analysis is only one of the many areas where the detector will have a great impact,鈥� he聽says.
