Weight based dual vapor adsorption analyzer

DVS ResolutionWeight based dual vapor adsorption analyzerInheriting the original DVS technology pioneered by SMS, and achieving breakthroughs on this basis, it provides excellent performance for measuring the adsorption behavior of solid materials on moisture and organic vapor, with accuracy and repeatability. It is very suitable for generating moisture adsorption isotherms, evaluating material moisture absorption, and studying adsorption kinetics.

DVS ResolutionWeight based dual vapor adsorption analyzerBy combining innovative design with high-precision humidity control, accurate and reliable vapor adsorption measurements can be achieved on various materials. The system uses a dry carrier gas (usually nitrogen or compressed air), combined with a mass flow digital controller, to accurately mix the dry airflow with the saturated vapor airflow, thereby generating a stable and controllable relative humidity environment.

The core of the instrument is SMS's proprietary Ultrabalance high-precision balance, which can measure the mass changes of samples in real-time during adsorption and desorption processes, enabling researchers to capture the detailed behavior of interactions between materials such as powders, films, fibers, and vapors. Optional modular accessories, such as in-situ preheating devices, further enhance the flexibility of the experiment.
