Application of High-Temperature High-Resolution Gas Chromatography to the Analysis of β-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.
