The DVS Resolution vapor sorption analyzer from Surface Measurement Systems is used to test the sorption properties of materials using the gravimetric method. Thanks to the advanced SMS UltraBalance™ measurement system, the device allows measurements of samples with masses in the range of 1-1000 mg with a resolution of 0.01 μg, in the temperature range of 5-85°C and relative humidity from 0 to 98% (±0.5%, 5-65 °C). Thanks to the use of mass flow controllers and a solvent vapor mixing collector, True0™, as well as thanks to a real-time humidity measurement probe and a Speed of Sound Sensor, it is possible to perform sorption measurements of water and a wide range of organic solvents with a P/P0 resolution of up to ±0.1%. A unique feature of our device is the fact that it has been adapted to work with the Edinburgh Instruments FS-5 UV-vis-NIR spectrofluorometer, which allows the study of the influence of solvent particles on the luminescent properties of materials in the simultaneous measurement of sorption and photoluminescence.
