WebMar 30, 2024 · The dynamic vapor sorption (DVS) method is an effective technique used to determine water diffusivities of cereal grains [ 4] and cereal-based foods [ 5, 6, 7] due to its convenient and precise control of both relative humidity (RH) and temperature. WebDynamic Vapor Sorption (DVS) is one popular way to analyze vapor sorption. Up until a few decades ago, a slow, manual process involving desiccators was the primary method of vapor sorption analysis. In 1991, Daryl Williams developed DVS to reduce the massive amount of time and manual labor that was required to get meaningful data.
