Diagram of the instrumentation used for the determination of pH inside of a liquid chromatograph using pH-sensitive dyes.
Dwight Stoll, Gabriel Leme, David Harmes, Joey Eikens (’16), and Ben Madigan (’20) (all Chemistry), along with co-authors from the University of Minnesota and Merck, Sharpe, and Dohme, published a methods paper in the journal Analytical Methods. The paper describes a novel approach to determine the pH inside of instrumentation for liquid chromatography, an environment that cannot be probed using conventional means. DOI: 10.1039/C8AY02496K.
