Izingxenye kanye nobuchwepheshe bezinhlelo ze-EDXRF
Uhlelo lwe-energy dispersive x-ray fluorescence spectroscopy luthembele kushubhu le-X-ray elizinzile kakhulu, igumbi lesampula elivikelwe kahle, kanye ne-electronics yokuthola ethuthukisiwe. Umthombo we-X-ray ukhiqiza umsebe ogxile ovusa ama-athomu ngaphakathi kwesampula eqinile. I-fluorescence ekhishwayo ibanjwa yi-silicon drift detectors, ethuthukisa ukuzwela ngokuletha amazinga aphezulu okubalwa ngomsindo ophansi we-elekthronikhi. Lokhu kuthuthukisa kokubili ukuphuma kanye nomkhawulo wokutholwa, okuvumela ukuhlukanisa okusheshayo phakathi kwezinto zokulandelela ngisho nasezindaweni ezingaphansi kwe-ppm.
Indlela i-EDXRF Esebenza Ngayo Ekuhlaziyweni Kwezinto Ezihlukahlukene
Izinhlelo ze-spectroscopy ze-x-ray fluorescence spectroscopy ezisabalala ngamandla zilandela ukuhamba komsebenzi okulula: ukubekwa kwesampula ngokulungiselela okuncane, ukushiswa kwemisebe nge-X-ray beam egxile, kanye nokutholwa kwe-X-rays enezici ezikhishwayo kusetshenziswa ama-detector e-silicon drift athuthukisiwe. Uhlelo lubamba i-spectrum ephelele, okuvumela ukutholwa okusheshayo, kanyekanye kwezinto eziningi.
Ukunqunywa kwezakhi ezinkulu nezilandelanayo kufinyelelwa ngokuhlaziya ubukhali bemigqa yokukhishwa kwegesi. Ezifundweni zesistimu ye-XRF ezijwayelekile zamandla elabhorethri, ukuphambuka phakathi kwemiphumela ye-EDXRF nezindlela ezijwayelekile kuhlala kungaphansi kuka-15% kohlu olubanzi lwe-matrices, okuletha ukunemba okuthembekile ekuqapheni kwemvelo kanye nezicelo zokumba.
Izinzuzo Eziyinhloko kanye Namakhono Ezinhlelo Zanamuhla Ze-EDXRF
Izinhlelo ze-spectroscopy ze-x-ray fluorescence spectroscopy zinikeza ukutholwa okusheshayo kwezinto eziningi, zibamba ama-spectra e-X-ray azo zonke izinto ezikhona ngesikhathi esisodwa. Kudingeka ukulungiswa okuncane kwesampula; amasampula ahlaziywa ngqo ngaphandle kokugaya noma ukuncibilika, okugcina ubuqotho kanye nokunciphisa ukuhamba komsebenzi. Indlela yokungabhubhisi iqinisekisa ukuthi amasampula ahlala engashintshi ukuze kuhlolwe okwengeziwe noma kugcinwe.
Ukuhlanganiswa kwezitholi ze-silicon drift kumathuluzi e-XRF athuthukile ahlukanisa amandla kuvumela ukunqunywa kwe-trace element kuze kufike ezingeni le-ppm kuzo zonke izinombolo ze-athomu kusukela ku-12 kuya ku-92.
Ukuguquguquka kokusetshenziswa kudlulela ekuhlaziyweni kwezinto eziqinile ezahlukahlukene, njengematshe, izimpushana ezicindezelwe, ama-polymer, kanye nama-alloy ensimbi. Ama-spectrometer e-XRF aphathwayo aphathwayo kanye nezinhlelo ze-XRF zamandla ezihlakazekayo zelebhu ye-benchtop zinikeza izilinganiso ezihambisanayo neziphindaphindayo ezibalulekile ekusebenzeni okuvamile kokulawula kwe-geochemical, kwemvelo, kanye nezimboni. Idatha isekela ukuhambisana nokulandelela emikhakheni elawulwayo.
Izinto Ezintsha Nentuthuko Yamuva Ku-EDXRF
Ukwethulwa kwe-silicon drift detectors kuphoqele ukulungiswa kwesistimu ye-X-ray fluorescence ethuthukisiwe ngaphansi kuka-150 eV ku-Mn Kα, okuvumela uhlelo lwe-XRF oluhlakazayo lwelabhorethri ukuthi lunikeze ukuhlukaniswa okucacile kwe-spectral phakathi kweziqongo eziseduze.
