Description:
X-ray diffraction is a valuable tool for the identification of crystalline compounds in a multicomponent sample. Two x-ray diffraction techniques (Seeman-Bohlin and Bragg-Brentano) were examined for the identification of small amounts of material deposited on low-mass substrates. The Seeman-Bohlin focusing camera has somewhat better resolution than the Bragg-Brentano diffractometer but the commercial availability of the automated diffractometer and the sophistication of the computer programs for identifying the crystalline compounds are decisive advantages. The tremendous potential of x-ray diffraction suggests that it should be added at this time to the stable of techniques for the characterization of pollution particulate samples.
