Specac offers an Environmental Chamber designed for use with the Selector™ Diffuse Reflectance Accessory. This Environmental Chamber extends the sampling capabilities of the Selector™ by allowing the study of a diffusely reflecting sample at temperatures up to 800°C and pressures from vacuum (0.001 Torr) to 500 psi. Solid or powder samples are placed onto a sampling cup within an atmospherically controllable chamber for DRIFTS spectroscopic analysis. This accessory is ideal for infrared spectroscopic analysis of kinetics, catalysis, surface analysis, polymerization, and coordination chemistry.
ZnSe windows are used as standard on the chamber, to give a good balance between wide mid-IR transmission and mechanical strength. Other windows are available on request. The main body of the Environmental Chamber is constructed from 316 stainless steel for both ruggedness and chemical resistance. A water cooling jacket keeps the outside of the chamber cool when operating at high temperatures and a safety ‘burst disc’ activates whenever the pressure exceeds the recommended safety limit.
The Environmental Chamber can only be used in conjunction with Specac’s Selector™ Diffuse Reflectance Accessory.
