Based on the properties of the corrected retention volume and, primarily, its independence from the carrier gas pressure, we concluded that the corrected retention volume cannot be a gas volume. We demonstrated that this parameter is identical to the volume of an ideal fluid required for the elution of a sorbate in an ideal chromatographic system. The corrected retention volume does not obey gas laws; because of this, numerous relationships obtained in gas chromatography without taking into account this property of the corrected retention volume should be revised. We considered publications of various authors in order to illustrate inconsistencies and contradictions that follow from the nonrecognition (or rejection) of this fact.
