Moisture sorption analysis is done to provide insight into a sample's stability and moisture adsorption properties. Used extensively in the pharmaceutical and food industries, moisture sorption analysis is a critical component when determining a product's shelf life, and potential degradation under varying environmental conditions. Moisture sorption analyzers are accurate and often modular instruments used to test these properties under various humidity and temperature conditions. When comparing different moisture sorption analysis instrumentation, ensure that the measurement mode will comply with your analysis needs, most models operate gravimetrically however some utilize spectroscopy for their analysis. Also ensure that the environmental controls can provide the temperatures, gasses, and humidity levels appropriate for your sample analysis. Many models of moisture sorption analyzers can also generate moisture sorption isotherms by creating a controlled humidity environment to study the relationship between the moisture content of a material and the relative humidity of the surrounding environment.

Measured vapor uptake isotherms and kinetics are used to characterize, test and evaluate materials in precisely defined environmental conditions.
An ultra-sensitive microbalance measures changes in sample mass as a function of humidity and temperature. Humidity is determined by relative mixing of wet and dry gas streams, and is measured and regulated at the sample position. These factors combine to offer unrivalled performance and total baseline stability.
