SEPARATION AND DETERMINATION OF INORGANIC ANIONS BY REVERSED-PHASE HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY

An overview and discussion is given of literature methods published af ter 1989 devoted to the ion-interaction chromatographic determination of inorganic anions. Seventy references are quoted. Ion-interaction ch romatography makes use of commercial reversed-phase stationary phase a nd conventional high-performance liquid chromatography instrumentation . The basis of the technique, the modification of the stationary phase surface, the choice of the ion-interaction reagent as well as the dep endence of retention on the different variables involved are discussed . Examples of application in the fields of environmental, clinical and food chemistry are presented. The experimental conditions of stationa ry phase, of mobile phase composition as well as detection mode, detec tion limit and application are also summarized in tables. (C) 1997 Els evier Science B.V.
