A novel detection method for high-performance liquid chromatography utilizes the addition of a colloidal suspension of solid reagent postcolumn to the eluant stream. The average particle size of the insoluble solid reagent is small enough to keep it in suspension. The solid reagent may react with the sample to reduce the background signal or may react with the eluite making it detectable. Since the reagent is solid, it is invisible to detectors that respond only to the liquid phase, e.g. conductometric and potentiometric detectors. This paper examines the properties of sulfonated polystyrene-type solid reagents and describes their application in conductivity detection. Other potential uses of the solid phase reagents are discussed.
