Gas chromatographic analysis of many surfactants has been limited due to tailing and adsorption of the analyte on the stationary phase of the column by polar groups such as hydroxyl and amine functionalities. Silylation of these surfactants reduces these unfavorable interactions by replacement of the active hydrogen with a silyl group Si−(CH 3 ) 3 . Although silylation generally is avoided in aqueious solutions some surfactants have been silylated successfully in aqueous solutions. These include fatty acids and their hydroxamine soaps, fatty and other alcohols, fatty amines, and some inorganic acids. Quantitative results have been confirmed by stoichiometric, gas chromatographic and infrared data.
