摘要
Packed column subcritical fluid chromatography of underivatized amino acids is described. Using pyridine (or ethylene glycol)-methanol-water-triethylamine as modifier in the carbon dioxide, mixtures of amino acids can be separated on diol-bonded silica and detected without derivatization using evaporative light-scattering detection. Pyridine and ethylene glycol are shown to impregnate the stationary phase and to improve efficiency. The results demonstrate the wide potential of packed column subcritical fluid chromatography for the determination of polar compounds.
