MADISON, Wis., July 22, 2013 — The DiffusIR reflectance accessory from Pike Technologies now offers a selection of environmental chambers. The accessory and chamber combinations enable catalytic research, including investigation of reaction pathways and determination of kinetics assays. Reaction gases may be flowed through the sample via porous ceramic sample cups. The quick-release feature provides for the sealed environmental chambers to be quickly inserted and removed from the accessory. The environmental chambers may be configured for temperatures from 150 to 900 °C. With the high-pressure adapter option, pressures up to 1500 psi may be achieved.
