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. Designed for operation from high vacuum (133 μPa or 10-6 torr) to 133 kPa (1 ktorr) with KBr windows or 1.5 MPa (11.2 ktorr) with ZnSe or SiO2 windows. Readily adapted for operation up to 3.44MPa (25.8 ktorr) with an optional high-pressure dome.
