Dynamic Dual Vapor/Gas Vacuum Gravimetric Sorption Analyzer
The world’s most versatile Vacuum DVS for the measurement of kinetics and physisorption isotherms of Zeolites, MOFs, COFs, Carbons, and composite materials.
DVS Vacuum offers dynamic or static sorption or co-adsorption experiments from low pressures up to 1bar. The system’s key features are precise control and measure of temperature and pressure while recording the changes in sample mass using high-resolution UltraBalace.
DVS Vacuum uses vacuum produced by combination of roughing and turbomolecular pumps for its operation – in-situ outgassing of sample up to 400oC and water or organic vapors generation at the set temperature. The vacuum chamber including sample, pressure transducers, vapor/gas delivery system and solvent flasks are at thermal equilibrium in a single temperature enclosure allowing smooth operation over the entire temperature range (20-70°C) without risk of condensation. The system introduces partial pressures of water or organic solvent under vacuum to minimize their impact on the structure of a material. The analyser measures true water or organic vapor sorption isotherms without unnecessary interference from a carrier gas. In addition, it allows to study drying kinetics of pharmaceutical powders.
