Fused-silica capillary columns were evaluated for the resolution of oxidized cholesterol derivatives. Thermal instability of diol derivatives, epimeric 7~ and 7fl-hydroxy, 4&hydroxy, and 25-hydroxycholesterol, was observed during gas chromatography. After derivatization as trimethylsilyl ethers the
Chemotaxonomic information can be extracted from microorganisms through gas chromatographic characterization of pyrolysate which is influenced by pyrolysis time and temperature, gas atmosphere for pyrolysis, and others. The quantitative effects of these parameters were determined using a pyrolysis g
