The Praying MantisTM(DRP) accessory

Company: Harrick

The Praying MantisTM was the first generally available diffuse reflection (DRIFTS) attachment and remains the forerunner in the field. It incorporates two 6:1, 90° off-axis ellipsoids which form a highly efficient diffuse reflection illumination and collection system. This unique configuration deflects the specular reflectance away from the collecting ellipsoid, minimizing the associated spectral distortions. The Praying MantisTM also can be configured to study materials and reactions in controlled environments with the appropriate diffuse reflectance reaction chamber.

The applications are:

  • Easy and reliable diffuse reflection analysis of solids and powders by FT-IR and UV-VIS spectroscopy
  • Analysis of catalysts and other powders in a temperature and/or pressure controlled enviornment
