The X-rays emitted by the sample being analyzed are collimated by parallel copper blades (called or ), and irradiate a known single at a precise angle. The single crystal the photons () which are collected by a detector, usually a or a .Wavelength dispersive Xray spectroscopy...
Wavelength-dispersive X-ray analysis (WDX or WDS)—Electron Probe Microanalysis (EPMA) Wavelength-dispersive spectroscopy (WDS) is the most directly comparable technique to EDX; both use electron-excited X-rays to allow characterization of a sample. The two techniques are often combined in EPMA (...
