Post-Column Chemistry for Improved Optical Absorption Detection
14 May 2013

This poster shows improved equipment for post-column chemistry suited for any liquid chromatography system. The flexibility of the reactor is demonstrated by optimizing four widespread post-column techniques: the relatively slow ninhydrin reaction with amino acids and the fast derivatizations of silicate, bromate, and chromate(VI). USP and EPA methods are performed accordingly.
