Application of High-Temperature High-Resolution Gas Chromatography to the Analysis of -Cyclodextrin Derivatives

Abstract

Short (3 m) columns are used with high-temperature stationary phases in analyses of reaction mixtures and isolated single species of β-cyclodextrin derivatives. The stationary phases are 5% phenyl-95% methylpolysiloxane and 30% diphenylpolysiloxane-40% sildiphenylene-ether-30% dimethyl polysiloxane; the latter phase is the best phase for the resolution of mixtures of positional isomers of β-cyclodextrin derivatives.
