Raws li nrog scanninge electron microscopy, electron sojntsuam microanalysis (EPMA) sojntsuam saum npoo ntawm tus qauv nrog lub zog hluav taws xob siab, yog li txhawb lub plhaub sab hauv ionization hauv cov atoms Qhov no ua rau lub emission ntawm tus yam ntxwv X-rays ua hauj lwm raws li kos npe ntawm lub ntsiab tam sim no.

microanalysis apparatus ua haujlwm li cas?

EPMA ua haujlwm los ntawm bombarding micro-volume ntawm tus qauv nrog lub teeb tsom electron(lub zog ib txwm=5-30 keV) thiab sau cov X-ray photons yog li tso tawm los ntawm ntau yam elemental hom.

microprobe ua li cas?

Ib electron microprobe (EMP), tseem hu ua electron sojntsuam microanalyzer (EPMA) lossis electron micro sojntsuam analyzer (EMPA), yog cov cuab yeej tshuaj xyuas siv los txiav txim siab tsis muaj tshuaj lom neeg muaj pes tsawg leeg. me me ntawm cov khoom siv.

Cov khoom siv microanalysis yog dab tsi?

Microanalysis yog ib txoj kev siv los soj ntsuam qhov pore qhov loj me ncaj qha tom qab nthuav cov qauv.

siv EPMA yog dab tsi?

Lub Electron Probe Micro Analyzer (tom qab no, "EPMA") yog ib qho cuab yeej los tshuaj xyuas cov ntsiab lus uas muaj cov khoom, los ntawm irradiating electron beams mus rau cov khoom nto thiab ntsuas cov yam ntxwv X-ray uas yog generated.
