This contribution evaluates the performance of two predictive approaches in calculating temperature-programmed gas chromatog. retention times under vacuum outlet conditions. In the first approach, the predictions are performed according to a thermodn.-based model, while in the second approach the predictions are conducted by using the temperature-programmed retention time equation. These modeling approaches were evaluated on 47 test compounds belonging to different chem. classes, under different exptl. conditions, namely, two modes of gas flow regulation (i.e., constant inlet pressure and constant flow rate), and different temperature programs (i.e., 7°C/min, 5°C/min, and 3°C/min). Both modeling approaches gave satisfactory results and were able to accurately predict the elution profiles of the studied test compounds The thermodn.-based model provided more satisfying results under constant flow rate mode, with average modeling errors of 0.43%, 0.33%, and 0.15% across all the studied temperature programs. Nevertheless, under constant inlet pressure mode, lower modeling errors were achieved when using the temperature-programmed retention time equation, with average modeling errors of 0.18%, 0.18%, and 0.31% across the used temperature programs.
