Manufacturer: Hiden Isochema
Model: IGAsorp Dynamic Vapor Sorption Analyzer
S/N: IG-SA-069
Description:
IGAsorp Dynamic Vapor Sorption Analyzer is a fully automated compact benchtop DVS analyzer, for fast and accurate sorption measurements using the dynamic flow technique for water and organic solvents. 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.
The IGAsorp uses the unique IGA method for the determination of the sorption kinetics and equilibrium isotherms. This ensures accurate and consistent analysis with faster analysis times making the optimum use of instrument time. Hiden Isochema’s unique IGA method is applied independently to every step in a gravimetric sorption measurement. At each step, the humidity and temperature are actively regulated, with resultant changes in sample weight continuously recorded. The kinetic weight data is analyzed in real-time, and the trend toward equilibrium is predicted and displayed on screen. Equilibration criteria are applied to objectively determine the period allowed before the measurement moves on to the next pressure or temperature value. Each equilibrium point is plotted on an isotherm or isohume, and the full raw data is also recorded. The IGAsorp therefore allows consistent analysis with optimum measurement accuracy and faster overall process times.
