Advanced materials analysis with Micro-XRF for SEM
Element analysis of samples using scanning electron microscopes (SEM) is widespread in materials science. A SEM provides not only topological information via surface images but also compositional information. In most cases, the microscopist will use energy-dispersive X-ray spectrometers (EDS) to analyze sample radiation created through the microscope’s electron beam.
This webinar discusses a complementary method: The use of a separate X-ray source equipped with polycapillary optics attached to the SEM to excite the sample and to evaluate the fluorescence radiation produced. This is known as micro-X-ray fluorescence spectrometry, or Micro-XRF for short. Bruker’s Micro-XRF for SEM uses the EDS’ silicon drift detector and signal processing chain to form a complete Micro-XRF spectrometer.
Although this method has been known for a number of years, its use in combination with a SEM is not very common, even though it has a range of benefits to offer. Our experts will explain this powerful addendum to EDS, which allows users to combine
- the light-element sensitivity of EDS with trace element analysis in the mid to heavy element range by Micro-XRF to improve the accuracy of quantification, and
- the surface sensitivity of EDS with the volume analysis capabilities of Micro-XRF.
The discussion of the technique will be complemented by the presentation of a number of application examples.
