## electron probe X-ray microanalysis (EPXMA)

https://doi.org/10.1351/goldbook.E02007
Any analytical technique which uses the excitation and evaluation of the characteristic X-ray spectrum of a solid specimen by a focused electron beam (typically of a diameter of less than $$1\ \unicode[Times]{x3BC}\text{m}$$). Qualitative and quantitative X-ray analysis is the main feature of EPXMA. For obtaining supplementary information the @S05518@, @B00583@ and @A00033@ are also frequently observed. Qualitative and quantitative X-ray analysis is, however, the main feature of EPXMA.
