Dvs water sorption
WebSince dynamic water vapour sorption is undoubtedly not a quick measurement, this design enables true simultaneous measurements, resulting in an obvious increase in analysis throughput. The new single sample Aquadyne DVS-1, however, offers a cost-effective solution to the analytical demands of those labs that don’t need that throughput. WebDynamic Vapor Sorption (DVS) is a gravimetric technique that measures the uptake and loss of vapour by a sample, enabling its physico-chemical & sorption behaviour to be accurately determined.

WebThe DVS method works well for investigating the kinetics of sorption—what happens to a product as it is exposed to certain humidities and how fast it adsorbs or desorbs water. The DVS method is not very helpful in creating a high-resolution isotherm curve, however, as each equilibrium step produces just one point on the isotherm curve.
