DVS Adventure -
Surface Measurement Systems
DVS Adventure is a water vapor sorption analyzer that measures sorption and desorption isotherms over a broad range of humidities and temperatures. It offers unprecedented temperature stability and humidity performance.
-
DVS Endeavour -
Surface Measurement Systems
A key feature of DVS Endeavour is the ability to precisely control and measure temperature and relative humidity while simultaneously recording the highest resolution changes in mass on up to 5 samples. Additionally Organic vapor partial pressures can now be directly measured using Surface Measurement Systems’ Speed of Sound sensor (patented).
-
DVS Vacuum -
Surface Measurement Systems
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 measure of temperature and pressure while recording the changes in sample mass using high-resolution UltraBalance.

DVS Resolution -
Surface Measurement Systems
DVS Resolution’s 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 realtime 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 300oC.
