<p>An improved apparatus and method for the quantitative analysis of a solution containing a plurality of anion species by ion exchange chromatography which utilizes a single eluent (14) and a single ion exchange bed (12) which does not require periodic regeneration. The solution containing the anions is added to an anion exchange resin bed (12) which is a low capacity macroreticular polystyrene-divinyl-benzene resin containing quarternary ammonium functional groups, and is eluted therefrom with a dilute solution (14) of a low electrical conductance organic acid salt. As each anion species is eluted from the bed (12), it is quantitatively sensed by conventional detection means such as a conductivity cell (20). </p> |
