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, or DVS, is a gravimetric technique that measures the mass of a sample as it changes in response to programmed changes in temperature or humidity. A typical experiment exposes a sample to an …

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.
