## Abstract Conversion of ethoxylated alcohols to trimethylsilyl derivatives and subsequent high temperature gas chromatography allowed for the determination of alkyl chain distribution, mole average degree of ethoxylation and weight percent distribution of several commercial mixtures. Repetitive d
Meibomian secretions from the hamster were hydrolysed with base and examined as TMS, IZH,ITMS, methyl ester/TMS, picolinyl ester/TMS and nicotinate/TMS derivatives by capillary G U M S . Over 90 compounds, representing over 89% of the hydrolysed fraction, were identified. Fatty acids with chain leng
Five seed oils consisting of unusual triacylglycerols have been examined by high temperature gas chromatography using glass capillary columns coated with the stationary phase SOP-50 (50%-diphenyl-50%-dimethylpolysiloxane, methoxy-terminated). The investigated hydroxy, epoxy, and ketokonjuene triacyl
