Hiden Isochema IGAsorp Dynamic Vapor Sorption Analyzer

The Hiden Isochema IGAsorp Dynamic Vapor Sorption Analyzer is a compact, fully automated benchtop instrument for gravimetric sorption measurements using dynamic flow technology. It measures water and organic vapor uptake isotherms and kinetics under precisely controlled humidity and temperature conditions.

An ultra-sensitive microbalance continuously records sample mass changes while humidity is generated by mixing wet and dry gas streams. Humidity and temperature are regulated at the sample position, supporting stable and reproducible sorption measurements for pharmaceutical, biotechnology, polymer, packaging, electronics, and natural-materials research.
