DVS Intrinsic-Image

The DVS Intrinsic - A compact and economical Vapor Sorption System.-

rapidly measures uptake and loss of moisture in the sample by flowing a carrier gas at a specified relative humidity (RH) over a sample suspended from the weighing mechanism of our highly sensitive and stable digital microbalance, the SMS UltraBalance, which detects the sorption/desorption of water vapor by the increase/decrease in mass of the material.

The instrument is capable of accommodating a sample mass up to 4g and with dimensions as large as 40mm, so many differing sample sizes and geometries can be easily accommodated. Changes in sample mass of 0.1μg and unrivalled long-term stability are hallmarks of the Intrinsic and which are required for the accurate measurement of water sorption phenomena.

These measurements may take from a few minutes to a few hours to complete depending upon the sample size and material. Indeed, a major factor in determining the water sorption behavior of materials is the need to establish rapid water sorption equilibrium. Therefore, the DVS Intrinsic also allows sorption behaviour to be accurately determined on very small sample sizes (typically 1-20 mg) thus providing great savings in the time required to reach equilibrium. Larger sample sizes can, however, easily be accommodated but typically require longer equilibration times.
