Abstract A polemic is given regarding the calculated thermodynamic quantities reported in the published paper by Farschi and coworkers. The graph used to calculate the molar heat of sorption of organic probe molecules onto the liquid DL-limonene stationary phase erroneously plots the reciprocal of the centigrade temperatures, rather than the reciprocal of the Kelvin temperatures. Molar heats of vaporization of the organic probe molecules reported in the paper are abnormally small and are not in accord with published values determined from calorimetric and vapor pressure measurements.
