Dynamic vapor sorption 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 is 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.
