Dvs isotherm analysis report
WebThe pore size distribution analysis obtained from the desorption isotherm always has the peak of 3.4 nm pore due to the pressure of cavitations. This pore needs to be ignored when using the desorption of N2 isotherm at 77 K because this is not related to the pore condensation on the material. WebSep 1, 2011 · The water sorption-desorption isotherms were obtained using a DVS system capable of resolving 0.1 μg. The accuracy of the system is ± 0.5% for the RH over a range of 0-98% and ± 0.3ºC for 25ºC. At 25ºC, …
