Yan Liu is the Director, Chemistry R&D in the Ion Chromatography and Sample Preparation Business Unit of Thermo Fisher Scientific. Yan joined Dionex now part of Thermo Fisher Scientific in 1988. Yan has been working on the research and development efforts in the area of ion chromatography systems, electrochemical detectors, and ion chromatography consumable products including electrolytic eluent generators, ion exchange columns, and suppressors. Yan has developed a number of novel electrolytic devices for the generation and recycling of acid, base, and salt solutions for use as eluents in ion chromatography systems. Yan has been instrumental in the development of capillary ion chromatography systems with electrolytic eluent generation and suppression. Yan has received 40 U.S. patents in the field of chromatography. Yan has authored and co-authored more than 45 peer-reviewed scientific papers. Yan received the Ion Chromatography Award in recognition of his sustained and significant contribution to the technical advancement of ion chromatography applications from International Ion Chromatography Symposium Scientific Organizing Committee on in 2011. Yan was a primary contributor for three RFIC systems that won the R&D Magazine’s R&D 100 Awards in 2009, 2011, and 2013. Yan received a B.S. degree in Analytical Chemistry from Xiamen University in 1982 and a Ph.D. degree in Analytical Chemistry from Oregon State University in 1987.
