Wavelength-dispersive X-ray spectroscopy (WDXS)
Wavelength-dispersive X-ray spectroscopy (WDXS or WDS) is a method used to count the number of X-rays of a specific wavelength diffracted by a crystal. The wavelength of the impinging X-ray and the crystal's lattice spacings are related by Bragg's law and produce constructive interference if they fit the criteria of Bragg's law. Unlike the related technique of energy-dispersive X-ray spectroscopy (EDS), WDS reads or counts only the X-rays of a single wavelength at a time, not producing a broad spectrum of wavelengths or energies simultaneously. WDS is primarily used in chemical analysis and has much higher accuracy and sensitivity than EDS analysis. For WDX samples should be flat and parallel on both sides, with one face well-polished.
In addition to this the AMC has:
- Mineral analysis
- Micro XRF analysis
