The IGA method
The unique IGA method allows simultaneous determination of sorption kinetics and equilibrium isotherms with exceptional accuracy. By optimizing how equilibrium is detected, the IGA method delivers high quality endpoint determination, consistent results, and shorter measurement durations.
Hiden Isochema’s unique IGA method is applied independently to every step in a gravimetric sorption measurement. At each step, the pressure 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 isobar, and the full raw data is also recorded.
The IGA method therefore allows consistent analysis with optimum measurement accuracy and faster overall process times.
