Gravimetric sorption
WebAnalysis results typically in just half the time needed by gravimetric methods. When analysis time is important, the VSTAR with its static volumetric system is the best choice. … WebIn the case of a dry powder absorbing water, the gravimetric sorption technique known as “dynamic vapour sorption” (DVS) assesses how quickly and how much of the solvent is absorbed by a sample. This is accomplished by altering the vapour concentration around the sample and observing the change in mass that results.

Sorption–desorption processes generally comprise multiple reactions or steps involving solid and aqueous phase components (Aha-roni and Sparks, 1991). The steps include transport processes ... WebA sandblast procedure was also tested for the maintenance stage, as a possible quick way to clean the tool. Gravimetric ageing of bulk plates was carried out on some of the fluids (water, cutting emulsion and dielectric fluid) and a dual-Fickian model was created in order to characterise their sorption process.
DVS measurement has applications over a wide range of industries. Both equilibrium vapor sorption isotherms and vapor sorption kinetic results can yield vital information for materials ranging from pharmaceuticals to fuel cells. Although water sorption experiments are most common, the use of organic vapor in DVS experiments can reveal additional sample properties. The below sections highlight how DVS experiments are utilized in several industries. WebThe LINSEIS Gravimetric Sorption Analyzer STA HP, which measures both weight change and DSC- signal, provides a much faster alternative. Within 15 minutes or less the sorption heats can be measured. Chemisorption and catalytic oxidation or reduction are exothermic re- actions. The heat involved can be easily monitored with the integrated DSC ...
