Ukushintsha Okuzenzakalelayo Phakathi Kwemigqa Ye-Spectral Eqinile Nebuthakathaka: I-AES-8000 Full-Spectrum AC/DC Arc Emission Spectrometer

Uma wenzaukuhlaziywa kwe-spectroscopy yokukhishwa komoya, uvame ukuhlangana nezinkinga ezilandelayo: imigqa ye-spectral ebuthakathaka iba buthaka kakhulu ngokutholwa kokugxila okuphansi, okuholela ekuphazamisekeni komsindo ngokweqile kanye nedatha engasetshenziswa; kuyilapho imigqa ye-spectral enamandla igcwala kalula futhi ihlushwa ukumuncwa kwayo ngesikhathi sokuhlolwa kokugxila okuphezulu, okuholela emiphumeleni yobuningi egobile kakhulu. Ukushintshana ngesandla phakathi kwemigqa ye-spectral akugcini nje ngokuthatha isikhathi kodwa futhi kuvame ukuba namaphutha. Manje, ukushintshana okuzenzakalelayo phakathi kwemigqa ye-spectral eqinile nebuthakathaka kuyatholakala:

II-spectrometer yokukhipha i-arc ye-AC/DC ye-AES-8000 egcwele i-spectrumI-BFRL ine-"inhlanganiso ehlakaniphile" yokuhlaziywa kwe-multi spectral line joint, exazulula amaphuzu abuhlungu okulinganisa ububanzi obugcwele ngokuchofoza okukodwa, okwenza ukuhlaziywa kwe-emission spectrum kusebenze kahle futhi kunembe kakhudlwana.

Kuyini ukuguqulwa okuzenzakalelayo kwemigqa ye-spectral eqinile nebuthakathaka?

Kalula nje, "ingumlawuli ohlakaniphile" wokuthola i-spectroscopy yokukhishwa. Ngesikhathi senqubo yokuthola, asikho isidingo sokungenelela ngesandla, futhi ingabuyisa ngokuzenzakalelayo imigqa ye-spectral ngamandla afanele ngesikhathi sangempela ngokusekelwe ekugxilweni nasekuqukweni kwento ngayinye, ifinyelele ekulinganisweni okunembile ngaphandle kwamaphutha kulo lonke uhla. Kungakhathaliseki ukuthi ukugxilwa okuphansi noma okuphezulu, asikho isidingo sokushintsha imigqa ye-spectral ngesandla. Isofthiwe ingajwayela ngokuzenzakalelayo ikhambi elifanele!

Inzuzo Eyinhloko: Kungani ingaba "inkosi yokusebenza kahle"?

Ukumbozwa okugcwele okubanzi: ukugxilisa okuphansi kuncike emigqeni eqinile ye-spectral ukuze kugcinwe ukuzwela, ukugxilisa okuphezulu kuncike emigqeni ye-spectral ebuthakathaka ukuze kugcinwe ukulingana, ngaphandle kwesidingo sokushintsha amapharamitha okulinganisa okuningi noma ukushintsha imigqa ngesandla, okuhlanganisa kalula lonke uhla lokugxilisa.

Ilwa nokuhlanekezela: Ukuqapha imigqa eqinile ye-spectral ngesikhathi sangempela, uma umkhawulo usufinyelelwe, ishintshela ngokuzenzakalelayo emigqeni ye-spectral ebuthakathaka, ixazulula ngokuphelele inkinga yokuphambuka kokulinganisa okuphezulu.

Ukunemba akuphazamiseki: Imigqa ye-spectral eqinile nebuthakathaka iyaphelelisana, igcina ukunemba okuphezulu ekuhlaziyweni okuhlangene kwemigqa ye-spectral eminingi.

Kufinyelela kanjani "ukushintsha okuhlakaniphile"?

Ukuqaliswa kwezinyathelo ezimbili zokuzivumelanisa okuzenzakalelayo, isimiso silula futhi kulula ukuyiqonda:

(1) Ukuba khona kwama-curve amaningi okusebenza: Isofthiwe iqoqa ngasikhathi sinye izimpawu zomugqa we-spectral wokuhlaziya eziningi zento efanayo enamandla nobuthakathaka obuhlukene, futhi ifanelana ne-curve yokusebenza yomugqa ngamunye we-spectral. Mane usethe umkhawulo wokuguqulwa ngokusekelwe ebangeni eliqondile le-curve ngayinye yokusebenza ukuze uqedele ukuqoqwa kwemigqa ye-spectral eqinile/ebuthakathaka.

(2) Ukushintshashintsha okunamandla: Okokuqala, sebenzisa imigqa eqinile ye-spectral ukuze ulawule ukulinganisa. Uma umphumela wokuthola usufinyelele umkhawulo, uzoshintshela ngokuzenzakalelayo emigqeni ye-spectral ebuthakathaka futhi ushintshe kalula kuyo yonke inqubo.

Izimo Zohlelo Lokusebenza

Ekunqunyweni kwesiliva (Ag), i-boron (B), i-tin (Sn), i-molybdenum (Mo), kanye ne-lead (Pb) kumasampula enhlabathi kanye ne-stream sediment embonini ye-geological, izinzuzo zokushintsha ngokuzenzakalelayo phakathi kwemigqa eqinile nebuthakathaka ziyabonakala ngokugcwele.

Ngokuqukethwe okuphansi kokuhlushwa, imigqa eqinile—i-Ag (328.068 nm), i-Sn (317.50 nm), i-B (249.773 nm), i-Mo (313.2594 nm), kanye ne-Pb (283.3069 nm)—ibamba ngokunembile izingxenye zokulandelela. Lapho ukuhlushwa kudlula umkhawulo wokushintsha umugqa, uhlelo lushintsha ngokuzenzakalelayo luye emigqeni ebuthakathaka ukuze lugweme ukugcwala, futhi lungenza ngisho nokushintsha okuningi (isb., kwe-Pb). Ngokuhlaziya okuhlangene kusetshenziswa imigqa eqinile nebuthakathaka, uhlelo alugcini nje ngokuhlangabezana nezidingo zokutholwa kwezinga eliphansi kodwa futhi luhlanganisa ububanzi bokutholwa obudingekayo besampula yenhlabathi kanye neyomfula.
