ATRspectroscopy Reflection methods, above all ATR spectroscopy, have gained increasingly in importance in conjunction with FTIR technology. They are used for samples with poor or no IR transparency, which cannot be analysed in transmission. One of the major advantages of ATR spectroscopy lies in that sample preparation becomes easier, and the need for complex sample preparation is often avoided completely. High mechanical stability and outstanding chemical resistance have made diamond ATR a highly versatile method for routine analysis of solid and liquid samples in many laboratories. We offer a full range of single reflection & multi reflection ATR accessories. Specular reflection Specular reflection technology analyses the radiation reflected from a surface. The amount of reflected light is dependent on the angle of incidence, refractive index, surface roughness and absorption properties of the sample. Typical applications are the analysis of surface coatings, e.g. surface-treated metals, paint, varnishes and polymers. The 30° reflection unit is ideal for routine analysis. The monolayer reflection unit enables the angle of incidence to be varied continuously within a range of 8° to 85° (grazing incidence). Diffuse reflection Rough surfaces or powder will respond to irradiation with light by predominantly diffuse reflection, with a certain degree of specular reflection. Accessories for measurement of diffuse reflection are therefore designed to optimally collect the diffuse portion whilst minimising the specular portion. The Selector diffuse reflection unit enables solid samples to be analysed without the need for extensive sample preparation. The optional pressure and temperature sample chamber allows analysis in a controlled atmosphere from room temperature up to 800 °C. The Minidiff Plus pre-aligned diffuse reflection unit is a low-cost alternative to the Selector diffuse reflection unit.
