Dynamic Vapor Sorption (DVS) Analysis

Dynamic Vapor Sorption (DVS) analysis is an analytical technique employed to quantify the vapor absorption and desorption behavior of materials as a function of relative humidity at a constant temperature (typically 25°C). This method is highly valuable for characterizing materials in industries such as pharmaceuticals, food products, and polymers.

In a DVS experiment, a sample is subjected to a controlled humidity program. The changes in the sample's mass are monitored as it absorbs or desorbs moisture. This process provides detailed information on the kinetics and thermodynamics of moisture sorption.

At Seven Star, we have a DVS Adventure instrument capable of recording light microscopy images to monitor changes in materials, such as deliquescence and particle agglomerations. Additionally, we have a DVS Intrinsic instrument that is equally capable of performing moisture sorption experiments, without light microscopy imaging.
