Micro X-ray fluorescence in materials characterization
Micro X-ray fluorescence ~MXRF! offers the analyst a new approach to materials characterization. The range of applications is expanding rapidly. Single point analysis has been demonstrated for nanoliter volumes with detection limits at the 0.5 ng level. MXRF can be used as an element specific detector for capillary electrophoresis. Elemental imaging applications include analysis of sample corro...
متن کاملImproved micro x-ray fluorescence spectrometer for light element analysis.
Since most available micro x-ray fluorescence (micro-XRF) spectrometers operate in air, which does not allow the analysis of low-Z elements (Z or = 6). It offers improved excitation and detection conditions necessary for light element analysis. To eliminate absorption of the ...
متن کاملDetermining the Content of Silicon Dioxide in Bauxites Using X-Ray Fluorescence Spectrometry
The X-ray fluorescence spectrometry and the MA.BM.006 reference spectrophotometric methods were used to determine the content of SiO2 (%) in bauxites from different deposits. The treatment of samples prior to the analysis involved the following steps: annealing, melting using the borax method, and the formation of beads. Certified reference bauxite samples were used for the cali...
متن کاملMicro X-ray diffraction and fluorescence tomography for the study of multilayered automotive paints
Combined microscopic X-ray fluorescence/microscopic X-ray diffraction (μ-XRF/μ-XRD) tomography is a recently developed method that allows the visualization of the distribution of chemical elements and the associated crystalline phases inside complex, heterogeneous materials of extended thickness (millimeter range) in a nondestructive fashion. In this paper, the accuracy and resolution with whic...
