Dynamic Vapor Sorption (DVS) instruments are commonly used to measure sorption isotherms on a diverse array of materials, including powders, fibers, films, particulates, and other solid surfaces.

These isotherms can be obtained with various gases and vapors over a wide range of temperatures. Isotherm size, shape and hysteresis can elucidate mechanistic information about vapor/gas-solid interactions. Further, by applying the correct isotherm models, it is possible to determine additional material properties, such as surface areas, monolayer capacities, micro- and meso-porosity, and sorption enthalpies. This educational and informational webinar focuses on the interpretation of isotherm attributes and the application of various surface and bulk isotherm models.
