The VSTAR system goes beyond basic water sorption to provide vapor and gas sorption analyses over a broad range of analysis conditions. Based on the fast and high-resolution vacuum-volumetric gas sorption technique, VSTAR can obtain analysis results in roughly half the time required by classical DVS methods. Wide chemical compatibility allows users to measure adsorption/desorption isotherms and kinetics of many species (organics, alcohols, amines, and more). The VSTAR system comes in two- or four-station versions for any level of throughput the user needs.
