In 1948–1950, Raimond Castaing, saib xyuas los ntawm André Guinier, tsim thawj lub tshuab hluav taws xob "microsonde électronique" (electron microprobe) ntawm ONERA.
electron microprobe siv rau dab tsi?
Ib qho khoom siv hluav taws xob micro-analyzer yog cov cuab yeej microbeam siv feem ntau rau qhov hauv qhov chaw tsis muaj kev puas tsuaj tshuaj ntsuam xyuas cov qauv ntsuas ntsuas. EPMA kuj tseem hu ua electron microprobe, lossis tsuas yog sojntsuam. Nws yog lub hauv paus zoo ib yam li SEM, nrog rau kev muaj peev xwm ntxiv ntawm kev tshuaj xyuas tshuaj.
Electron microprobe tsom xam yog dab tsi?
Electron microprobe tsom xam (EMPA) muab cov ntaub ntawv ntawm cov tshuaj muaj pes tsawg leeg ntawm cov zaub mov thiab lawv cov kev sib raug zoo hauv archaeological ceramicslos ntawm kev siv cov nqaj nqaim hluav taws xob los txhawb cov emission ntawm X-rays.
Yuav ua li cas lub tshuab tsom iav yog lub microprobe?
Electron microprobes tau nruab nrog optical microscopesco-axial rau cov kab hluav taws xob tau teeb tsa hauv txoj hauv kev uas thaum tus qauv saum npoo yog nyob rau hauv kev ua kom pom tseeb nrog cov khoom siv kho qhov muag / lub koob yees duab, nws kuj yog nyob rau hauv X-ray tsom xam, piv txwv li, nws nyob ntawm Rowland lub voj voog.
Leej twg tsim lub SEM?
Siv cov khoom siv hluav taws xob, uas muaj qhov luv luv luv dua li lub teeb, nws tuaj yeem daws cov khoom ntawm tus kheej ntawm qhov kev nthuav dav dua. Plaub xyoos tom qab, Max Knoll nrhiav pom ib txoj hauv kev los cheb ib lub teeb hluav taws xob hla lubnto ntawm tus qauv, tsim thawj scanning electron microscope (SEM) cov duab.
