Dynamic vapor sorption 意味
WebDynamic Vapor Sorption (DVS) is a gravimetric sorption technique that measures how quickly and how much of a solvent is absorbed by a sample: such as a dry powder absorbing water. It does this by varying the vapor concentration surrounding the sample in a controlled environment and measuring the change in mass that this produces. While … Webchanges in relative humidity. Dynamic vapor sorption (DVS) analysis is a technique specifically designed to provide such information. EXPERIMENTAL . In a typical DVS experiment, the relative humidity (%RH) is stepped from a low initial level (either ambient or 0 %RH) to a high level (90-95 %RH), then back down to a
