dvs-resolution-second

Incorporating an innovative design, the DVS Resolution provides accurate precision sorption measurements on a huge range of materials. Employing a dry carrier gas, typically Nitrogen or compressed air, the instrument uses digital mass flow controllers to regulate flows of dry and saturated gases. By precisely mixing dry and saturated gas flows in desired flow ratios, precision levels of relative humidity are generated.

With the Surface Measurement Systems Ultrabalance™ measuring minute real-time mass changes caused by sorption and desorption in the sample, valuable sorption behaviors can be observed in a range of materials. The DVS Resolution can function with a range of modular accessories (I.e. in-situ pre-heater), greatly expanding its experimental capabilities. As the most advanced and versatile DVS instrument on the market, the DVS Resolution is the leading sorption analyzer in the world.

By precisely mixing dry and saturated gas flows in desired flow ratios, precision levels of relative humidity are generated.

With the Surface Measurement Systems Ultrabalance™ measuring minute real-time mass changes caused by sorption and desorption in the sample, valuable sorption behaviors can be observed in a range of materials. The DVS Resolution can function with a range of modular accessories (I.e. in-situ pre-heater), greatly expanding its experimental capabilities. As the most advanced and versatile DVS instrument on the market, the DVS Resolution is the leading sorption analyzer in the world.
