The Specac Minidiff Plus Diffuse Reflectance Accessory allows economic and high quality DRIFTS (Diffuse Reflectance Infrared Fourier Transform Spectroscopy) analysis of a wide variety of powders and solid samples. Typically, a small amount of sample is ground with KBr powder for analysis. Applications include characterisation of polymers, catalysts, films, fibres, powdered chemicals, and pharmaceuticals.

Pre-aligned optics ensures maximum optical throughput and ease of operation of the accessory. Sampling versatility is maintained through the use of sampling cups to hold powdered or particulate materials, and diabrase abrasive sampling pads for scraping non particulate solid materials. The sample holder platform is simply and easily removed and reinstalled in the accessory, and brought into position with a micrometer focus adjustment without need for re-alignment of the optical components.

This accessory is installed with Specac’s Benchmark™ type baseplate system. It is supplied together with sample cup holders, abrasive sample holders, diabrase abrasive pads, KBr powder, and a pestle and mortar as standard.
