The introduction of Dynamic Vapour Sorption (DVS) in 1994 revolutionised the field of gravimetric moisture sorption measurement, bringing outdated, time and labour intensive desiccator use into the modern world of cutting-edge instrumentation and overnight vapour sorption isotherms. All models are designed, developed and produced by SMS, and now include the SMS UltraBalance at the heart of the system.

DVS is a valued tool in laboratories all over the world, within R & D from polymorphism and compound stability studies to bulk and surface adsorption effects of water and organic vapours. It𠏋 a vital part of quality control analysis techniques for both scale-up and production, and can even be found within the packaging arena, measuring both the efficacy and permeability of packaging, and the effects of humidity and temperature on the samples within the packaging.
