Analyze water and hydrocarbon vapor sorption on materials using the IGA-002

Hiden Isochema's IGA-002 gravimetric analyzer is designed to analyze the general vapor sorption processes under vacuum conditions. It features all the components of the IGA-001 model in addition to anti-condensation protection feature rated to 50°C and an additional low range pressure sensor.

The system can be integrated with a UHV pump isolation valve to achieve a high vacuum at the sample position. Further, the pressure controller is added with a vapor delivery system. The system consists of a number of sample environment options with a wide operating temperature range from -196°C to 1000°C and pressure range from ultra-high vacuum to 20 bar.

The IGA-002 has a unique design with the combination of accurate computer control and measurement of temperature, pressure and mass change. This enables automatic determination of gas and vapor sorption-desorption isotherms and isobars under different operating conditions.

The IGA-002 is used for analyzing water and hydrocarbon vapor sorption on a number of materials including polymers, clays, zeolites, catalysts, carbons, and pharmaceuticals.
