The IGA method
The XEMIS employs the unique IGA method to determine both 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.
Real-time kinetic analysis is achieved through continuous monitoring of weight-time data. The software models this data and predicts the trend toward equilibrium, which is clearly displayed on-screen. Objective equilibrium criteria are automatically applied to determine the optimal point to proceed – ensuring reliable, repeatable measurements.
