Superior data quality meets unparalleled ease-of-use The D2 PHASER delivers data quality and collection speed that, up to recently, was thought impossible with a benchtop XRD system. The powder X-ray diffraction instruments are located in IATL 196 and managed by Dr. The D2 PHASER is a desktop diffractometer for all X-ray powder diffraction applications in Bragg-Brentano geometry. The database, in combination with the analysis software, allows for quick and easy identification of phases within geologic samples, corrosion products, or other solid-state materials. With a variable Z-axis on this instrument, materials up to 30 mm in height can be placed on a flat holder and a surface can be analyzed.įor PXRD data analysis, the facility maintains a license for the ICDD PDF 4+ powder diffraction database along with analysis software Jade, Eva, and Topas. This instrument is also equipped with a standard Cu source, variable slits (for Bragg-Brentano beam geometry) or Cross Beam Optics (for parallel beam geometry), and a D/teX position-sensitive solid-state detector. This instrument is designated to analyze both powder and non-powder crystalline samples (films, metals, rocks, etc.). For powder diffraction, everything is a sample the technique is commonly applied to characterize minerals, ceramics, metals and alloys, catalysts, polymers, pharmaceuticals, organic compounds. The second PXRD instrument in the facility is a Rigaku SmartLab. For most users, data collection times range from 5-30 minutes depending on the crystallinity of their materials. Ewald 1916 published a simple and more elegant theory of X-ray diffraction by introducing the reciprocal lattice concept. The instrument also hosts a 9-position sample changer with sample rotation capabilities to automation of data collection. This instrument is equipped with a standard Cu source, variable slits (for Bragg-Brentano beam geometry) or Göbel mirrors (for parallel beam geometry), and a Lynx-Eye position-sensitive solid-state detector for high-speed data collection. For the analysis of powders (grain sizes in the range of 20 µm) the Bruker D8 Advance diffractometer is the preferred instrument. The powder X-ray diffraction instrumentation in the facility is designed for the analysis of polycrystalline materials.
