X-ray fluorescence microscopy x-ray fluorescence microprobe (XFM) analysis XFM https://orcid.org/0000-0001-5985-7429 X-ray fluorescence imaging XRF imaging 2009-08-26T05:09:12Z CHMO:0002311 An imaging technique where a beam of X-rays is directed at the specimen and the intensities of the X-rays emitted due to core-to-core transitions (known as 'X-ray fluorescence') are detected as a function of wavelength and position. As these energies are element-specific, X-ray fluorescence microscopy can be used to determine spatially-resolved elemental composition. X-ray microscopy
