Powder XRD provides detailed information on the crystallographic structure and physical properties of materials and thin films.The sample is irradiated with a beam of monochromatic x-rays over a variable incident angle range. Interaction with atoms in the sample results in diffracted x-rays when the Bragg equation is satisfied. Resulting spectra are characteristic of chemical composition and phase. The technique uniquely provides phase identification (e.g. graphite or diamond), along with phase quantification, % crystallinity, crystallite size and unit cell size. For layered materials, Grazing Incidence XRD (GIXRD) allows compositional depth profiling of phases within the structure.
96-cell microplate reader
SEM provides detailed high-resolution images of the sample by rastering a focussed electron beam across the surface and detecting secondary or backscattered electron signal.
