โœฆ Synopsis

A method is described for the. determination of polyethylene glycol in polyethers, referred to as condensates, derived from reaction between ethylene oxide and fatty alcol~ols, alkyl phenols, fatty amines and alkanolamides. The method is based on liquid partition chromatography using sodium chloride solution as the stationary phase, ethyl acetate as the, moving phase, and cellulose as the column support. The conditions required for complete separation and recovery are described.

Three alternative procedures for the determination of non-ionic surfactants (NS) in surface water have been developed. The simplest one consists of the filtration of water samples, the extraction of NS with ethyl acetate, the evaporation of the solvent and the determination of NS using an indirect

Matrix-assisted time-of-flight mass spectrometry (MALDI-TOFMS) has been shown to be a useful tool for the analysis of a wide range of biological and synthetic polymers. This has included the analysis of some commercial formulations of some non-ionic surfactants. But, as yet, no one has reported the
