  • Title: Retention and separation studies of cholesterol and bile acids using thermostated thin-layer chromatography.
    Author: Zarzycki PK, Wierzbowska M, Lamparczyk H.
    Journal: J Chromatogr A; 1999 Oct 01; 857(1-2):255-62. PubMed ID: 10536844.
    Abstract:
    The influence of temperature on retention and separation of cholesterol and bile acids, using reversed-phase thin-layer chromatography, was studied. As mobile phases methanol-water mixtures of various compositions were used. Chromatographic experiments were performed using vapor-saturated chambers at temperatures ranging from 5 to 60 degrees C. A linear relationship between R(M) values and temperature (1/T) as well as mobile phase composition was observed. The elution order of steroids under the conditions investigated was discussed. Each chromatogram was evaluated using simple optimization parameters and the best chromatographic conditions for the separation of multicomponent samples were chosen.
