Temperature Independent Retention in Gas Chromatography

Abstract

THE infinite dilution net retention volume (solubility) of solutes in GLC is related to the corresponding partition coefficient K^∞ and solvent volume V_L via Although V_L usually increases slightly with increasing temperature, K diminishes so rapidly that dV_R/dT is inevitably negative. The possibility that means may be found to cause V_L to increase with increasing temperature faster than K decreases seems never to have been explored although it obviously presents an approach to practical attainment of a novel GLC situation in which, at least for some range of temperature, d V_R/dT is positive or, more interesting, can be made zero.
