Product Overview

The IGA-100 is designed for gravimetric multi-component gas sorption, as well as single component vapour sorption analysis. The multiple inlet mass flow controller system allows multi-component experiments in both pressure control and flow control modes. The IGA design integrates precise computer-control and measurement of mass change, pressure and temperature to enable fully automatic and reproducible determination of gas and vapour sorption-desorption isotherms and isobars in diverse operating conditions.

Anti-condensation protection to 50 ºC is incorporated in the IGA-100, which allows operation with water and an extensive range of hydrocarbon vapours. Additionally, a range of sample environment options are available to allow operation at temperatures from -196 to 1000 °C and at pressures ranging from ultra-high vacuum to 20 bar. Product desorption and standard TG/MS experiments can be performed with the close-coupled mass spectrometer option. The versatile IGA-100 has been widely used for the study of sorption on catalysts, carbons, zeolites and polymers.
