The Discovery SA Dynamic Vapour Sorption Analyser measures how materials take up and release moisture with exceptional precision, allowing researchers to characterise humidity-dependent behaviour quickly and reliably. It exposes samples to tightly controlled changes in relative humidity and temperature, tracking minute mass variations in real time. This enables detailed assessment of sorption–desorption isotherms, hygroscopicity, phase transitions, stability, and kinetic processes across a wide range of biological, food, polymeric, and pharmaceutical materials—supporting both routine quality control and advanced research within the analytical facility.
