Abstract

Water activity measurement systems and methods for determining water activity of material samples in a test environment under controlled temperature and pressure conditions. The gas pressure in a test chamber is reduced or held constant while sample temperature is simultaneously tracked. The water activity of the sample can be determined by detecting the boiling point of the sample, at reduced pressure, over time, and calculating water activity using the atmospheric pressure and the saturation vapor pressure at the boiling temperature. The boiling point can be determined by observing an inflection point in the sample temperature over time, and the pressure and temperature at the onset of boiling can be determined at an intersection of trend lines extending from substantially linear intervals of temperature recordings over time.
