Performance and Application Comparisons for Single and Three Reflection Diamond Crystals for the MIRacle ATR Accessory

17 Sept 2015

Single reflection attenuated total reflection (ATR) accessories have become a leading sampling tool for Fourier transform infrared (FTIR) spectroscopy due to the ease and speed of sampling by this method. Further advancement in ATR sampling comes from the optimization of the ATR crystal choice and optical features, particular diamond, which provides a unique, long lasting and chemically inert sampling medium and its use grows as users discover the benefits of this material. IR absorption by the sample can be optimized for high concentration and low concentration components, by adjusting for angle of incidence of the IR beam or the refractive index of the ATR crystal, for example. This application note characterizes the performance of single and three reflection diamond ATR crystal plates using the MIRacle™ ATR accessory.

Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.Surface Area TestingPhysisorption studies fundamental parameters essential for the characterization of materials such as the specific surface area and pore size distribution. Properties such as porosity, strength, hardness, permeability, separation selectivity, corrosion, and thermal stress resistance can all be directly correlated to the porous structure of a material.Refractive IndexDiamond
