The 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 be directly measured using Surface Measurement Systems’ Ultrasonic sensor (patent pending). In a typical experiment a known concentration of water vapor or organic vapor is delivered over a sample placed inside the sample pan. The sample pan is connected to the Surface Measurement Systems UltrabalanceTH measuring real-time mass changes caused by sorption or desorption of water and/or organic molecules.
