About This Product

Adsorption of vapor onto porous materials is important and essential in many industries. Traditional gravimetry methods are based on the use of "static" vacuum techniques. This method is limited by the fact that "outgassing" of the vacuum chamber contents significantly contributes to the measured pressure and thus to the sorption measurements. Vacuum measurement DVS Vacuum allows you to obtain accurate adsorption properties of materials using solvents and gases.

■Important measurement functions

・Adsorption and desorption under dynamic, static, isothermal or isobaric conditions ・Competitive adsorption of two probe molecules (i.e. CO2 -H2O, toluene-H2O, MeOH-H2O) ・Implementation of multi-component experiments using adsorbed substance molecules for steam and gas ・Unique steam temperature and delivery control ・On-site sample degassing in high vacuum (2×10-6 Torr) up to 400℃ ・Multiple adsorption/desorption cycles and sample regeneration cycles ・Real-time adsorption reaction kinetics and thermodynamics ・Low experimental background pressure of 1×10-6 Torr ・Adsorption measurements at relative pressures as low as 0.005 Torr ・Minimum deliverable relative water vapor pressure at 25℃ 0.05% ・Sample mass: 5 to 1,000 mg
