What is Dynamic Vapor Sorption?

Dynamic Vapor Sorption (DVS) is a gravimetric sorption technique that measures how quickly and how much of a solvent is absorbed by a sample: such as a dry powder absorbing water. It does this by varying the vapor concentration surrounding the sample and measuring the change in mass which this produces.
Water vapor is most commonly used, but it is also possible to use a wide range of organic solvents.

Dynamic vapor sorption is a valued tool in laboratories, 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.
