英文摘要: A novel approach has been established to predict the retention time in operating parameter programmed gas-liquid chromatography with capillary columns through the use of numerical calculation, which can be applied to multi-ramp programs for column temperature and/or carrier gas pressure at the column inlet. The results show that a better or, at least similar accuracy, can be achieved for the prediction of retention time in temperature-programmed gas chromatography with the approach reported herein, than that obtained with Curvers' approach, which has been widely utilized up to now. Our established procedure is particularly suitable for those operating conditions containing an inlet pressure program. In addition, the prediction of resolution under temperature-programmed conditions from the trajectory of the solute band moving in the column, column efficiency and other operating parameters is discussed.
