Dvs isotherm

WebFull-featured DVS and high resolution DDI isotherm creation and analysis to help you: Identify critical moisture ranges with high resolution DDI isotherms; Study sorption kinetics with DVS isotherms; Identify critical … Webchannel hydrate using DVS. The resulting isotherm exhibited strong Langmuir/Type I behaviour. DR analysis was used to determine a channel pore volume of 0.0353 cm 3 /g. The ability of the DVS instruments to perform 0.2% RH steps below 10% RH and true zero RH functionality greatly enhanced the isotherm quality for these types of materials.
