The dynamic vapor sorption is used on a wide range of materials and fields. It is applied in pharmaceutics for salt-screening and to analyse polymorphism, in food industry to evaluate stability and shelf life studies.
It is a valuable tool to assess the caking behavior of powdered and granular material during transport, storage and handling. In material science, it is used to analyse water uptake and release of construction materials made of wood, plaster, fibres or concrete.
The operation principle is to measure the change in mass over time of a sample kept in an environment of controlled temperature and relative humidity. Change in mass is due to either water uptake (sorption) or through water release (desorption). In the conservation field, DVS is frequently used to evaluate the moisture behavior of material like parchment, wood, salts, leather.
The SciCult laboratory is equipped with a Vsorp Enhanced having a temperature and relative humidity range between 15 and 40°C, and 0 to 95%, respectively. The instrument can run up 23 samples simultaneously. It requires minimum ca 50 mg of sample.
