IGA-001 for Gravimetric Gas Sorption analysis

Hydrogen storage with IGA-001.

The IGA-001 is the original member of the IGA series of vacuum microbalance systems for high resolution measurements of gas sorption over a wide range of pressures and temperatures. The gravimetric sorption method, with real-time kinetic analysis provides unique information about sorption processes and phenomena.

The IGA-001 is used in a wide range of different industries and research fields, for characterisation of porous and non-porous materials.

Some typical applications for the IGA-001 include…

Sorption capacity and kinetics for:

Sorption isotherms for a wide range of gases
Isotherm mapping and PCT measurements up to 20 bar
Gas solubility
Kinetics, Transport and Diffusion coefficients
Differential Heat of sorption, Differential Entropy of Sorption

Physisorption

Physisorption isotherms for a wide range of gases.
BET Specific Surface Area and porosity (N₂, CO₂, or other gases)
Sorption capacity
Sorption thermodynamics
Diffusion analysis
In Situ degas/activation

Hydrogen Storage:
