Key Features

● 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.

 

Application Areas  

▲ Particularly suitable    ● Somewhat suitable ○ Can be used

▲ Infrared spectroscopy adsorption characterization and catalyst acidity determination.

▲ Chemical adsorption characterization and activity characterization of small molecules such as CO, NO, CH₃OH, C₂H₅OH on the catalyst surface.

▲ Determination of acidic sites on the catalyst surface using ammonia, pyridine, etc.

 

Technical Specifications

● Pressure Limits: Glass four-stage diffusion pump 10-6 Pa; Molecular turbo pump 10-9Pa.
