Description

Introducing IGA-001

The IGA-001 is a dedicated single component gas sorption analyzer for the study of gas interactions with both solids and liquids. Incorporating an ultra-sensitive microbalance, the IGA-001 measures changes in sample mass as a function of temperature and pressure. The unique IGA method analyzes real time gravimetric data to determine kinetic parameters and simultaneously predict sorption equilibrium.
