● Professional in-situ infrared characterization testing component designed to meet the requirements for in-situ infrared characterization testing of samples and can be used in conjunction with domestic and international infrared spectrometers such as Bruker, Nicolet, and PE.
● The system offers high gas-tightness, making it suitable for the high vacuum requirements necessary for in-situ infrared characterization experiments.
● The device is made of glass material, eliminating the impact of metal adsorption on experiments from a structural perspective and avoiding mutual interference of probe molecules.
● Transmission-type in-situ cell capable of processes such as sample baking, flowing oxidation-reduction, vacuum degassing, and adsorption reactions.
▲ Particularly suitable ● Somewhat suitable ○ Can be used
▲ Infrared spectroscopy adsorption characterization and catalyst acidity determination.
