Abstract: Two-dimensional retention times and peak widths in temperature programmed comprehensive two-dimensional gas chromatography were predicted using a theoretical model developed from experimental data obtained under isothermal conditions. A Matlab program was written to calculate the following parameters: dead time (t(M)), elution temperature (T(e)), retention time (t(R)), hold-up width (w(M)) and peak width (w(R)). The two-dimensional retention times of a sample mixture that contained n-alkanes and polyaromatic h…
