Moisture Sorption Method for Hygroscopic Samples Using a Modified Proximity Equilibration Cell

Abstract

ABSTRACT The study was undertaken to develop a suitable design to accommodate liquefying hygroscopic samples in the Proximity Equilibrium Cell (PEC) for equilibration to desired water activity. The system suggested has overcome the limitation of the earlier reported methods using PEC and is found to be rapid compared to other gravimetric methods used for hygroscopic materials.
