Xa kufikwa kwii-atomic emission spectrometers, uninzi lwabantu lucinga ngoko nangoko nge-ICP-AES okanye mhlawumbi ii-spark direct-reading spectrometers. Bambalwa abakhankanya ii-arc emission spectrometers. Sekunjalo, njengelungu elidala losapho lwe-atomic emission spectrometers, le teknoloji ibe negalelo elikhulu kwiminyaka emininzi edlulileyo kuhlalutyo lwekhwalithi kunye nolwamanani lwezinto ezingaphiliyo kwimimandla efana nophando lwejoloji, iimetali ezingezizo iiferrous, kunye nesayensi yezinto.
Nanamhlanje, ngenxa yezixhobo ezikumgangatho ophezulu ezifumaneka ngokubanzi, iingenelo zayo—ezifana nohlalutyo oluthe ngqo lweesampuli zomgubo kunye nobuntununtunu obuphezulu—ziye zayigcina iyindlela ekhethiweyo yokuchonga isilivere, i-boron, kunye ne-tin kwishishini le-geological. Ihlala isisixhobo esibalulekileyo kwiilabhoratri ze-geological kwaye ikwayindlela ecetyiswayo eqhelekileyo yokufumanisa izinto ezingcolisayo kwiintsimbi ezicocekileyo kakhulu ezifana ne-tungsten, i-molybdenum, i-niobium, kunye ne-tantalum, kunye nee-oxides zazo.
I-spectrograph yakudala ekhula ngokukhula
Okokuqala, masiqhelane “namaqhawe” e-arc emission spectrometry. Ii-atom spectrometers zokuqala ze-arc arc zazisebenzisa iipleyiti zefoto ukuze zibambe ii-emission spectra kwaye zazibizwa ngokuba zii-spectrographs. Ibali laqala ngo-1969 xa umanduleli weBeijing Beifen Ruili Analytical Instruments (Group) Co., Ltd.—Beijing No. 2 Optical Instrument Factory—yayiphuhlisa ngempumelelo i-one-meter plane grating spectrograph. Le modeli isabonakala rhoqo kwiilabhoratri ezininzi namhlanje.
I-spectrograph yemitha enye
Esi sixhobo sasifana “ne-darkroom master” enobuchule. Nangona sasinzima ukusisebenzisa (sifuna amanyathelo okucubungula iifoto), uvakalelo lwaso olukhethekileyo lwabeka isiseko sohlalutyo lwe-arc spectral kwaye sasingenakutshintshwa ngelo xesha. Usenokuba ubukhe wabona neemodeli ezinkulu—ii-spectrographs ze-grating zeemitha ezimbini ezinomgqomo omkhulu oluhlaza.

Imangalisa kangakanani loo "bhareli enkulu" yeemitha ezimbini ubude? Ngoku, jonga le bhemoth ingaqhelekanga ngezantsi. Kuthiwa inobude obuyimitha eziyi-3.4, obungafanelekanga kwilabhoratri eqhelekileyo, kwaye ikwaxhotyiswe ngomthombo omkhulu wokukhanya.

Inkqubo Yokufumana Idatha Eyinkimbinkimbi
Ukufumana idatha kwi-spectrograph kwakunzima kwaye kunzima: emva kokulungiselela isampuli, kwenziwa i-spectrograph. Emva kokuba igqityiwe, isibambi sepleyiti yokufota kwakufuneka sisuswe sisiwe kwigumbi elimnyama. Phantsi kokukhanya okubomvu okufipheleyo, ipleyiti yaphuhliswa, yalungiswa, yaza yahlanjwa—inkqubo efana nokwenziwa kweefoto ezimnyama nezimhlophe.
Ipleyiti ecociwe ngononophelo inokuba mnyama ngokupheleleyo ngenxa yokuchatshazelwa kakhulu, nto leyo enokwenza wonke umsebenzi wangaphambili ungabi namsebenzi. Kungenjalo, ngenxa yeengxaki zomphuhlisi okanye umlungisi, ipleyiti inokuba mnyama kakhulu okanye ilula kakhulu ukuba ingasetyenziswa, nto leyo ebangela ukuba iqalise kwakhona.
Igumbi elimnyama
Ngenxa yobuninzi bemigca ye-emission spectral, kwakufuneka uyihlolisise phantsi kobukhulu obuphezulu, ukhethe imigca yohlalutyo yento nganye ekujoliswe kuyo nganye nganye. Uhlalutyo lobungakanani lwalufuna ukulinganisa uxinano lwayo kusetyenziswa i-densitometer. Kwanakubahlalutyi abanamava, oku kwakungelula; kwabaqalayo, yayiliphupha elibi. Amehlo axineneyo ngenxa yokujonga imigca, kodwa kuchongwe imigca embalwa yohlalutyo.
Izinzwa zeMifanekiso Zithatha Indawo yeePlati zeMifanekiso
Ngenxa yokuqhubela phambili kwetekhnoloji, itekhnoloji yesenzi somfanekiso yavuthwa yaza yafumana usetyenziso kumashishini onke. Kanye njengokuba iikhamera zedijithali zathatha indawo yeekhamera zefilimu, isenzi somfanekiso saguqula i-arc emission spectrometry ngokutshintsha iipleyiti zemifanekiso zemveli. Zisebenzisa isiphumo sefotoelectric, ezi senzi ziguqula imiqondiso ye-optical ibe yimiqondiso yombane, ekugqibeleni ziyenza idijithali ukuze iboniswe ngqo kwisoftware yekhompyutha—isusa inkqubo enzima yokufumana idatha ye-spectrographs zemveli.
Utshintsho lokwenyani luqale phakathi kowama-2011 nowama-2014.I-BFRLiqalise uthotho lwe-AES-7000—utshintsho oluphazamisayo oludibanise uhlalutyo lwe-arc source spectral kunye neetyhubhu ze-photomultiplier (PMTs) ukuze kufezekiswe “ukufunda ngokuthe ngqo.” Abasebenzisi ekugqibeleni bakhululwe kumanyathelo anzima afana nokucubungula iipleyiti kunye nokulinganisa uxinano, nto leyo ephucula kakhulu ukusebenza kakuhle kwaye ikhawulezisa ukwamkelwa kobu buchwepheshe kwi-geology nakwi-metallurgy.
Nangona uthotho lwe-AES-7000 lwalukhawuleza, lwalunemida—imigca yalo ye-spectral yayilungisiwe. Ngo-2017,I-BFRLIthathe elinye inyathelo phambili ngokuqaliswa ngokusesikweni kwe-spectrometer yesizukulwana esilandelayo se-arc emission, i-AES-8000. Esi sixhobo safumana amandla e-spectrographs ze-grating ze-one-meter zemveli—ukutshintsha i-current/direct current (AC/DC) arc excitation, inkqubo yokukhanyisa ye-lens ezintathu, kunye nendlela ye-optical ye-Ebert-Fassie yakudala—ngexesha isamkela i-sensor ye-CMOS esebenza kakuhle yokubona isignali. Yakhiwe ngokutsha ngokupheleleyo, yafikelela kwinqanaba ukusuka “ekwazini ukuba ikhona” ukuya “ekuboneni konke.” Ilula ukuyisebenzisa, ikhawuleza, kwaye ilula, i-AES-8000 yajongana ngqo namanqaku entlungu abasebenzisi be-spectrograph kwaye ngokukhawuleza yaba yimveliso ephambili kwisizukulwana esitsha se-arc emission spectrometers.
✔ Uphuhliso Lokusebenza: Ukwamkelwa komxube we-“Ebert-Fassie optical system + CMOS detector”. Uvakalelo lwe-CMOS luphindwe kaninzi kunolwe-CCDs eziqhelekileyo, kwaye xa ludibene ne-patented optics, ukuphazamiseka kwangasemva kuyancitshiswa.
✔ Uyilo oluPhambili: Uhlalutyo olupheleleyo lwe-spectrum. Aluzange lusombulule nje kuphela umngeni weshishini wokulinganisa ngokuchanekileyo izinto ezifana nesilivere, i-tin, kunye ne-boron kwiisampulu zejoloji kodwa lukwahlangabezana neemfuno ezichanekileyo zemigangatho yesizwe.
✔ Amava akrelekrele: Ukulungelelaniswa kwee-electrode ngokuzenzekelayo, ukuvalwa kokhuseleko, ukulungiswa kwemvelaphi yesoftware ngokuzenzekelayo—ezi mpawu zikrelekrele zenza isixhobo singaneli nje ukuba sichaneke kodwa sibe “lula ukuyisebenzisa” kwaye sikhuseleke ngakumbi.
