IGA- 100 gravimetric gas sorption analyzer

The IGA-100 is an advanced gravimetric sorption analyzer, powerfully combining high resolution vapor, mixed gas and TGA-MS measurements. A multiple inlet flow control system allows mixed gas experiments with combined pressure, flow and composition control, while anti-condensation protection and active pressure regulation enable high resolution vapor sorption-desorption measurements.

BENEFITS OF IGA-100

• Unparalleled functionality for vapors, mixtures and high pressure gases
• Unrivalled measurement precision, accuracy and repeatability
• Fast and accurate analysis of equilibria and kinetics using the IGA method

THE IGA METHOD

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. 

APPLICATIONS

IGA analyzers are widely regarded as the benchmark for gravimetric sorption analyzers and are used in an extensive range of applications:

• Gas adsorption capacity determination
• Moisture and organic vapor sorption
• Catalyst characterization
• Moisture and organic vapor sorption with diffusion coefficient determination
• Thermogravimetric Analysis (TGA) and Evolved Gas Analysis (EGA)
• Temperature Programmed Desorption/Oxidation/Reduction (TPD, TPO, TPR)

IGA instruments are used in both academic and industrial laboratories globally and are continuously producing high precision reproducible data. The IGA’s reputation is underpinned by publication of data in over 700 peer reviewed papers, including many in high profile journals.
