Abstract
A thermoelectric method is described by which the difference of vapor pressure between 2 solutions, or between a solution and the pure solvent, can be measured. The principle involved is simply that of a differential wet-bulb thermometer of high sensitivity. A reading is obtained in 30 to 45 min. and the average error of a single observation is of the order of 1 1/2% of the difference read.Keywords
