Description

This is a valued tool in laboratories globally, within research and design, from polymorphism and compound stability studies to bulk and surface sorption effects of water and organic vapours. It is a vital part of quality control analyses and can even be found within the packaging industry to measure the effects of humidity and temperature on the contents.

The DVS is used worldwide to rapidly measure uptake and loss of moisture or organic vapours by flowing a carrier gas at a specified relative humidity over a sample suspended from the weighing mechanism of an ultra-sensitive recording microbalance.

More examples of DVS applications include moisture uptake behaviour of food and natural materials, stability and caking of food ingredients, moisture diffusion into blister packaging systems, moisture sorption of hydrophobic pharmaceutical materials, surface energies and surface areas of powders using organic vapour probes, determination of deliquescence points, moisture-induced glass transition in an amorphous material, determination of amorphous contents, pharmaceutical stability, drying and thermal degradation, adsorption of porous materials.
