Dynamic vapor sorption references
Dynamic vapor sorption (DVS) is a gravimetric 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. WebWater vapor sorption is an extremely valuable tool for comparing polymeric films used for packaging drugs and other humidity sensitive products.The plot below compares sorption …
