Product Description

Automatic Chemical Adsorption Analyzer  Gas Adsorption Instrument  Specific Surface Area Analyzer

The GA-1200 series chemical adsorption analyzer is an important characterization equipment for in-situ characterization of catalysts/analysis of surface active site characteristics. It is widely used in fields such as catalysts, fuel cells, energy storage materials, catalytic cracking, catalytic hydrogenation, catalytic reforming, water gas conversion, and automotive exhaust purification. By using the principle of continuous flow chromatography and programmed temperature rise technology, TPAT analysis of various inorganic/organic gases, pulse chemical adsorption, surface reaction, and specific surface area testing are achieved. At the same time, it can be combined with various detection devices, such as online mass spectrometry MS, chromatographic GC, infrared, gas analyzers, etc., to improve the synchronous detection accuracy of complex reactions and products.
