Knowledge of low vapor pressures p0 is indispensible for modeling the fate of chemicals in the environment as well as for other important applications. The indirect determination of vapor pressures by the capillary gas-liquid chromatography-relative retention time (GLC-RT) technique has attracted the attention of many research groups, and two review papers devoted to this topic have already been published. To complement these reviews, the quality of the literature vapor pressures for reference compounds is analyzed, along with the influence of the equations used for the temperature dependence of p0 and the effects of the extrapolation interval applied. In an effort to allow potential users to make an informed decision about what reference data and/or methodology to use to improve the reliability of the GLC-RT based vapor-pressure data, we present a set of recommendations and advisories for appropriate reference data use and manipulation.
