摘要：

A calculation procedure for multi-step temperature programmed gas chromatographic retention times and that was investigated over diverse temperature programme conditions is described. Thermodynamic parameters of components, calculated from their Kovats retention indices and the isothermal retention times of n-alkanes, are utilized in the procedure. The influence of column dead time and variations of Kovats retention indices is examined. The calculation accuracies are better than 1% in most instances. A live retention time database for multi-step temperature programming was constructed using this procedure.
