Measurements of Low Vapour Pressures

Article metrics

Abstract

THE two well-known methods of measuring vapour pressures are the statical and the dynamical. In the former the pressure exerted by a vapour is measured when the substance is kept at a given temperature, while in the latter the temperature is ascertained at which the liquid boils when under a given pressure. The present volume is mainly concerned with the description of, and the results obtained by, a dynamical method of estimating very low pressures for mixed as well as for pure substances; the pressure range extending, in general, from about zero to a maximum which is below 70 mm.
