Resumen:
A method to measure solvent evaporation rates under controlled conditions is described. Vapors generated within a thermostated glass cell are swept by a nitrogen current and periodically injected into a chromatographic column and detector by means of an automatic sampling valve. Solvents with evaporation rates equal to or lower than that of cyclohexane may be studied. As the evaporative cooling is negligible, the method offers a definite advantage over classical gravimetric techniques.
