Uma kukhulunywa ngama-spectrometer okukhipha ama-athomu, abantu abaningi bacabanga ngokushesha nge-ICP-AES noma mhlawumbe ama-spectrometer okufunda ngqo kwe-spark. Bambalwa abakhuluma ngama-spectrometer okukhipha ama-arc. Kodwa-ke, njengelungu elidala lomndeni wama-spectrometer okukhipha ama-athomu, lobu buchwepheshe bube negalelo elikhulu eminyakeni edlule ekuhlaziyweni kwekhwalithi kanye nokwenani kwezinto ezingaphili emikhakheni efana nokuhlola i-geological, izinsimbi ezingezona i-ferrous, kanye nesayensi yezinto.
Ngisho nanamuhla, njengoba izinsimbi ezisezingeni eliphezulu zitholakala kabanzi, izinzuzo zayo—njengokuhlaziywa okuqondile kwamasampula empuphu kanye nokuzwela okuphezulu—kuye kwayigcina iyindlela ekhethiwe yokunquma isiliva, i-boron, ne-tin embonini ye-geological. Ihlala iyithuluzi elibalulekile emalabhorethri e-geological futhi iyindlela ejwayelekile enconywayo yokuthola izinto ezingcolile ezinsimbini ezihlanzekile kakhulu njenge-tungsten, i-molybdenum, i-niobium, ne-tantalum, kanye nama-oxide azo.
I-spectrograph yakudala ekhula ngokukhula
Okokuqala, ake sijwayelane “nama-veteran” e-arc emission spectrometry. Ama-atomic spectrometer okuqala e-arc asebenzisa amapuleti ezithombe ukuze abambe ama-emission spectra futhi abizwa ngokuthi ama-spectrograph. Indaba yaqala ngo-1969 lapho umanduleli weBeijing Beifen Ruili Analytical Instruments (Group) Co., Ltd.—Beijing No. 2 Optical Instrument Factory—yathuthukisa ngempumelelo i-plane grating spectrograph enemitha elilodwa. Le modeli isalokhu iyinto evamile emalabhorethri amaningi namuhla.
I-spectrograph yemitha eyodwa
Leli thuluzi lalifana “nenkosi yegumbi elimnyama” ecophelelayo. Nakuba lalinzima ukulisebenzisa (lidinga izinyathelo zokucubungula izithombe), ukuzwela kwalo okungavamile kwabeka isisekelo sokuhlaziywa kwe-arc spectral futhi lalingenakutshintshwa ngaleso sikhathi. Kungenzeka ukuthi ubuke namamodeli amakhulu—ama-spectrograph amamitha amabili ane-“barrel” enkulu eluhlaza.
ama-spectrograph e-grating amamitha amabili
Imangalisa kangakanani leyo "bhareli elikhulu" elingamamitha amabili ubude? Manje, bheka lesi sithombe esikhulu ngezansi. Kuthiwa sinobude obungamamitha angu-3.4, okungafaneleki nhlobo elabhorethri evamile, futhi sihlonyiswe ngomthombo omkhulu wokukhanya ovusa inkanuko.

Inqubo Yokuthola Idatha Eyinkimbinkimbi
Ukuthola idatha ku-spectrograph kwakuyinto eyisicefe futhi eyinkimbinkimbi: ngemva kokulungisa isampula, kwenziwa i-spectrograph. Uma isiqediwe, isibambi sepuleti lezithombe kwakufanele sisuswe bese siyiswa egumbini elimnyama. Ngaphansi kokukhanya okubomvu okufiphele, ipuleti lathuthukiswa, laqiniswa, futhi lagezwa—inqubo efana nokuthuthukisa izithombe ezimnyama nezimhlophe.
Ipuleti elicutshungulwe ngokucophelela lingase libe mnyama ngokuphelele ngenxa yokuchayeka ngokweqile, okwenza wonke umsebenzi wangaphambilini ungabi namsebenzi. Ngaphandle kwalokho, ngenxa yezinkinga ngonjiniyela noma umlungisi, ipuleti lingase libe mnyama kakhulu noma likhanye kakhulu ukuba lingasetshenziswa, okuphoqa ukuqala kabusha.
Igumbi elimnyama
Ngenxa yobuningi bemigqa ye-spectral yokukhishwa, kwakudingeka uyihlole ngaphansi kokukhulisa okuphezulu, ukhethe imigqa yokuhlaziya yento ngayinye eqondiwe ngayinye. Ukuhlaziywa kwenani kwakudinga ukulinganisa ubuningi bayo kusetshenziswa i-densitometer. Ngisho nakubahlaziyi abanolwazi, lokhu kwakungelula; kwabaqalayo, kwakuyiphupho elibi. Amehlo ayekhathele ukubuka imigqa, kodwa kwatholakala imigqa embalwa yokuhlaziya.
Izinzwa Zezithombe Zithatha Indawo Yamapuleti Ezithombe
Ngokuthuthuka kwezobuchwepheshe, ubuchwepheshe bezinzwa zesithombe bavuthwa futhi bathola izinhlelo zokusebenza kuzo zonke izimboni. Njengoba nje amakhamera edijithali athatha indawo yamakhamera efilimu, izinzwa zezithombe zashintsha i-arc emission spectrometry ngokufaka esikhundleni amapuleti ezithombe endabuko. Besebenzisa umphumela we-photoelectric, lezi zinzwa ziguqula izimpawu ezibonakalayo zibe izimpawu zikagesi, ekugcineni zizenze zibe yidijithali ukuze ziboniswe ngqo kusofthiwe yekhompyutha—kuqedwe inqubo enzima yokuthola idatha yama-spectrograph endabuko.
Ushintsho lwangempela lwenzeka phakathi kuka-2011 no-2014.I-BFRLyethule uchungechunge lwe-AES-7000—ubuchwepheshe obusha obuhlanganisa ukuhlaziywa kwe-arc source spectral nama-photomultiplier tubes (PMTs) ukuze kufezwe “ukufundwa okuqondile.” Abasebenzisi ekugcineni bakhululiwe ezinyathelweni ezidinga umsebenzi omkhulu njengokucubungula amapuleti kanye nokulinganisa ubuningi, okuthuthukisa kakhulu ukusebenza kahle kanye nokusheshisa ukwamukelwa kwalobu buchwepheshe kweze-geology kanye ne-metallurgy.
Nakuba uchungechunge lwe-AES-7000 lwalushesha, lwalunemikhawulo—imigqa yalo ye-spectral yalungiswa. Ngo-2017,I-BFRLyathatha elinye igxathu phambili ngokwethulwa ngokusemthethweni kwe-spectrometer yokukhipha i-arc yesizukulwane esilandelayo, i-AES-8000. Le thuluzi lazuza amandla e-spectrographs yendabuko ye-grating yemitha elilodwa—ukushintshanisa i-arc current/direct current (AC/DC), uhlelo lokukhanyisa olune-lens ezintathu, kanye nendlela ye-optical yakudala ye-Ebert-Fassie—ngenkathi isebenzisa inzwa ye-CMOS esebenza kahle kakhulu yokuthola isignali. Njengoba ihlelwe kabusha ngokuphelele, yafinyelela igxathu kusukela “ekwazini ukuthi ikhona” kuya “ekuboneni konke.” Kulula ukuyisebenzisa, ngokushesha, futhi kulula, i-AES-8000 yabhekana ngqo namaphuzu obuhlungu abasebenzisi be-spectrograph futhi ngokushesha yaba umkhiqizo oyinhloko esizukulwaneni esisha se-arc emission spectrometers.
✔ Ukuthuthuka Kokusebenza: Ukwamukelwa kwenhlanganisela ethi “Ebert-Fassie optical system + CMOS detector”. Ukuzwela kwe-CMOS kuphindwe kaningana kunokwe-CCD ezivamile, futhi uma kuhlanganiswa ne-optics enelungelo lobunikazi, ukuphazamiseka kwangemuva kuyancishiswa.
✔ Ukusungula Izinto Eziyisisekelo: Ukuhlaziywa kwe-full-spectrum kwangempela. Akuzange kuxazulule kuphela inselele yemboni yokulinganisa ngokunembile izinto ezifana nesiliva, i-tin, ne-boron kumasampula e-geological kodwa futhi kwahlangabezana nezidingo zokunemba kwezindinganiso zikazwelonke.
✔ Ulwazi Oluhlakaniphile: Ukulungiswa kwama-electrode okuzenzakalelayo, ukukhiya kokuphepha, ukulungiswa kwesizinda sesofthiwe okuzenzakalelayo—lezi zici ezihlakaniphile zenza ithuluzi lingagcini nje ngokuba linembile kodwa futhi libe “lula ukulisebenzisa” futhi liphephe kakhudlwana.

Kusukela kokwakudala kuya kokusungula izinto ezintsha, bese kuba okwakudala futhi. Ekuthuthukisweni kwama-spectrometer okukhipha i-arc, imizamo yeBeijing Beifen-Ruili Analytical Instruments (Group) Co., Ltd. ibonisa indlela ecacile "yokudluliselwa kobuchwepheshe," njengoba kuboniswe yizibuyekezo zomkhiqizo wayo. Ngokuzithuthukisa okuqhubekayo, inkampani ivuselele inqubo "yasendulo" yokuhlaziya enkathini yobuchwepheshe obuhlakaniphile.
