description

Abstract Sodium 1-heptanesulphonate is used as an ion-pair reagent for the chromatographic separation of the two developing agents on a phenylsilica micro-column, with amperometric detection at an applied potential of + 0.75 V (vs. Ag/AgCl). No pretreatment of the developer is necessary. Linear calibration graphs were obtained in the range 10 −5 -1.5 × 10 −4 M.
