X-ray fluorescence spectrometers use high-energy X-rays or gamma rays to excite fluorescent radiation (or photons) from a sample for chemical or elemental analysis. In an energy dispersive X-ray fluorescence spectrometer (EDXRF Spectrometer), the fluorescent photons from the irradiated sample are detected without being separated first (as they are in wavelength dispersive XRF spectrometers). Therefore, EDXRF spectrometers typically have better efficiency, whereas WDXRF spectrometers have better resolution. Energy Dispersive XRF Spectrometers are used to analyze solid samples and although they have broad applications as disparate as petrochemical analysis, food safety, and plastics, one of the main attractions of this technique is that it is non-destructive, which makes it very attractive for analysis of samples that are irreplaceable, such as artifacts from an archeological site. The limit of detection for EDXRF spectrometers is typically in the parts per million (ppm) range.
