The Praying Mantis™ High Temp. Reaction Chamber is particularly effective for powders that have high surface areas. This makes diffuse reflectance a valuable tool for studying heterogeneous catalysis, gas-solid interactions, photochemical reactions, and oxidation mechanisms. This High Temperature Reaction Chamber is well suited for performing such studies under carefully controlled temperatures and pressures. High Temp. Reaction Chamber applications allow diffuse reflection (DRIFTS) spectroscopic measurements under controlled pressures and a wide range of temperatures. It is used in conjunction with the Praying Mantis™ Accessory for FT-IR and UV-VIS diffuse reflectance spectroscopy. Also available for Raman spectroscopy.
