Purnendu K. (Sandy) Dasgupta is a native of India and was educated in a college founded by Irish missionaries. By now he has spent most of life, virtually all his adult life in the US, Sandy has never been quite sure what to do with himself. In his mother tongue, Bengali, he is a well-published poet, in various magazines as well. He managed to get a diploma as a TV mechanic but finally found his love of analytical chemistry as salvation. He joined Texas Tech in 1981 and named a Horn Professor in 1992, named after the first president of the University, the youngest person to be so honored at the time. He remained at Texas Tech for 25 years, joining the University of Texas at Arlington in 2007 where is now Jenkins Garrett Professor and the Chair of the Department. He has written more than 400 papers/book chapters, and holds 23 US patents, including the electrodialytic reagent generation and suppression technologies on which current ion chromatography is based. His most recent labor of love is a 1000+ page undergraduate text on Quantitative Analysis, Coauthored with Gary Christian and Kevin Schug.   His awards include American Chemical Society (ACS))  National Award in Chromatography, ACS Southwest Region Chemist of the year award, The Doherty Memorial Award of the Dallas/Ft Worth ACS Section, Dal Nogare Award in Chromatography, Honor Proclamation by the State of Texas Senate,   the Dow Chemical Company Traylor Creativity Award, the Ion Chromatography Symposium Outstanding Achievement Award (twice once in 1989, once in 2005), the Benedetti-Pichler Memorial Award in microchemistry, William J. Probst Lecturer Award, Achievement Rewards for College Scientists (ARCS) Scientist of the Year Award, Best Science Paper of the Year Award, Environmental Science and Technology, 2005. He has been the Royal Australian Chemistry Institute roving analytical chemistry lecturer in 2003 and in 2007, Miegunyah Fellow at the University of Melbourne. He is the Editor of Analytica Chimica Acta, a major international journal in analytical chemistry. His work on perchlorate, an environmental contaminant, has attracted worldwide attention. In 2005, he was asked to brief the US congress on the significance of the widespread occurrence of perchlorate in human milk. Sandy, oddly enough, is in the English law books. In 1994, he testified as the principal expert witness in the Royal High Courts of Justice for Hoechst-Celanese against British Petroleum. The case involved the purification of acetic acid to remove iodide impurities by ion exchange resins. The judgment, £120 million against BP, was the highest ever awarded in a patent lawsuit in Britain.  Sandy has rather eclectic research interests, the present flagship project in his lab is a NASA-sponsored effort to build an ion chromatograph for extraterrestrial explorations.
