Application of Dynamic Vapour Sorption Technique to Study Dry …
WebThe 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. DDI isotherms reveal what hasn’t been seen before. The dynamic dew point isotherm (DDI) method was designed to solve this problem. It creates high-resolution isotherms that show ... WebTA Instruments invites you to experience the world’s most productive Dynamic Vapor Sorption (DVS) Analyzer, the Discovery SA. Discover the advanced engineering and attention to detail that provides … WebThe hysteresis between the adsorption isotherm and desorption isotherm is thought to be caused by the gradual desorption mechanism (percolation theory) due to the different size pores being combined. This percolation theory suggests that the pore size distribution obtained from the desorption isotherm is problematic to be used. export teams private chat
