The AquaLab Vapor Sorption Analyzer (VSA) allows scientists to better understand moisture in products and pinpoint quality control issues, according to manufacturer Decagon Devices. The way a product is influenced by temperature and humidity changes can reveal important details about physical and chemical changes that end shelf-life. This type of measurement is called an isotherm.
Isotherm generation technology tracks changes in the amount of moisture in a product as the water activity changes. Isotherms hold the key to understanding hidden details of food and pharmaceutical products. The AquaLab VSA is a moisture sorption analyzer that combines dynamic and traditional isotherm methods in one instrument.
According to the company, the AquaLab VSA provides hundreds of data points, showing details such as glass transition and greater resolution while still viewing reactions such as crystallization. The AquaLab Vapor Sorption Analyzer provides valuable insight into new product development, shelf-life estimation, packaging calculations, temperature abuse modeling and component mixing models in hours instead of weeks, the company added.
