The world’s most versatile Vacuum DVS for the measurement of kinetics and physisorption isotherms of Zeolites, MOFs, COFs, Carbons, and composite materials.
The DVS Vacuum is designed for single and multicomponent vapor/gas sorption analysis, supporting static and dynamic experiments. The system’s key features are precise control and measurement of temperature and pressure while recording the changes in sample mass using high-resolution UltraBalance.
DVS Vacuum uses a vacuum produced by a combination of roughing and turbomolecular pumps for its operation – in-situ outgassing of samples up to 400 °C and water or organic vapors generation at the set temperature. The vacuum chamber including the 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 a vacuum to minimize their impact on the structure of a material. The analyzer measures true water or organic vapor sorption isotherms without unnecessary interference from a carrier gas. In addition, it allows us to study the drying kinetics of pharmaceutical powders.
DVS Adventure is a water vapor sorption analyzer that measures sorption and desorption isotherms over various humidities and temperatures. It offers unprecedented temperature stability and humidity performance. It provides valuable information about the interactions of a sample with water vapor, which is critical for developing new materials and processes. For example, in many industries, water sorption properties of raw materials are considered key parameters in determining their storage, stability, processing, and application performance.
DVS Resolution is a dual vapor gravimetric analyzer, with key feature, is the combined ability to precisely control and measure temperature and relative humidity while recording the highest resolution changes in mass. DVS Resolution uses a dry carrier gas typically nitrogen or compressed air for its operation. Digital mass flow controllers regulate flows of dry and saturated gases.
Relative humidity is generated by precisely mixing dry and saturated gas flows in desired flow ratios which produce expected relative humidity. In a typical experiment, a known concentration of water vapor is delivered over a sample placed inside the sample pan connected to the Surface Measurement Systems UltraBalance™ measuring real-time mass changes caused by sorption or desorption of water molecules. Prior to sorption measurements, the sample can be in-situ preheated/dried at temperatures of up to 200 C.
