Determination of Dicyandiamide with Non-Aqueous Polar Eluent

Abstract

Epoxy powder paints are characterized by their dicyandiamide content. Dicyandiamide is determined on a amino bonded phase column with non-aqueous but polar eluent consisting of methanol and acetonitrile (5/95, v/v). The elution order of the components is that of normal phase but the eluent is more like reversed phase. This method is essentially faster than the previous methods in the analysis of dicyandiamide in multicomponent powder extracts.
