Diffuse Reflectance FTIR Accessory
Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is an in-situ technique. It obtains valuable information about surface reactions by tracking and characterizing adsorbed species formed during reactions on catalysts, so as to analyze the reaction mechanism. This characterization method is suitable for direct measurement of solid powder samples and surface analysis of materials. Sample preparation is simple; pellet pressing is not required, and the original morphology of samples is preserved. In-situ analysis can be carried out under different temperatures, pressures and gas atmospheres.
Two Configurations:
High-temperature low-pressure reaction chamber (HVC-DPR). Vacuum: 1 × 10⁻⁶ torr; Temperature: RT – 910 °C ( under vacuum ). An optional high-pressure dome is available, with pressure up to 3.4 MPa.
Low-temperature reaction chamber (CHC-CHA). Pressure range: atmospheric pressure to high vacuum (1 × 10⁻⁶ torr);
Temperature range: −150 °C – 600 °C ( under vacuum ).
Three inlet/outlet ports, supporting two gas feed lines and one vacuum pumping line.
Constructed of 316L stainless steel for chemical corrosion resistance.
The HVC-DPR can be optionally coated with inert Silcotek coating for improved corrosion resistance. Interchangeable window.
Compatible with UV diffuse reflectance and FTIR diffuse reflectance measurements.
Compatible with various FTIR spectrometers from Thermo Fisher (Nicolet), Bruker, etc.
