[Research on the separation of three isomers of hydroxybenzoic acid by capillary zone electrophoresis].
The separation behavior of o-hydroxybenzoic acid, m-hydroxybenzoic acid and p-hydroxybenzoic acid in high performance capillary zone electrophoresis was investigated using cetyltrimethylammonium bromide (CTAB) as reversed reagent for electroosmotic flow. The effects of pH of buffer solution and volume fraction of methanol on the separation, peak shape and elution order were studied.
