ABSTRACT:
A versatile and highly sensitive procedure of indirect photometric chromatography in which a variable capacity pH dependent weakly basic or weakly acidic ion exchange medium is used in the chromatographic column to effect ion separations. Adjusting eluent pH allows increased detection limits without extended analysis time, reduced column efficiency, or the need for a battery of conventional strongly basic/acidic ion exchange columns.
