Paired -Ion Chromatography (PIC Reagents) provide an easy solution for analyzing samples containing ionic species. These reagents allow ionic compounds to be separated by reverse-phase chromatography, saving time by allowing simultaneous assay of acids, bases, amphoteric and neutral compounds. PIC Sample Kit is one vial each of : WAT085101 PIC A, WAT085110 B5, WAT085140 B6, WAT085103 B7, and WAT085142 B8.
