Xa usenzaUhlalutyo lwe-spectroscopy yokukhupha umbane, uhlala udibana nale micimbi ilandelayo: imigca ye-spectral ebuthathaka iba buthuntu kakhulu xa kubonwa uxinano oluphantsi, nto leyo ebangela ukuphazamiseka kwengxolo egqithisileyo kunye nedatha engasetyenziswayo; ngelixa imigca ye-spectral enamandla igcwala lula kwaye ifumana ukufunxwa kwayo ngexesha lovavanyo loxinano oluphezulu, nto leyo ekhokelela kwiziphumo zobungakanani ezigoso kakhulu. Ukutshintsha ngesandla phakathi kwemigca ye-spectral akuthathi ixesha nje kuphela kodwa kukwanokuba neempazamo. Ngoku, ukutshintsha ngokuzenzekelayo phakathi kwemigca ye-spectral eqinileyo nebuthathaka kuyafumaneka:
II-spectrometer yokukhupha i-arc ye-AC/DC ye-AES-8000 epheleleyoI-BFRL ine "indibaniselwano ekrelekrele" yohlalutyo lwe-multi spectral line joint, esombulula iindawo ezibuhlungu zokulinganisa uluhlu olupheleleyo ngokucofa kanye, okwenza uhlalutyo lwe-emission spectrum lusebenze ngakumbi kwaye luchaneke.
Yintoni ukuguqulwa ngokuzenzekelayo kwemigca ye-spectral enamandla nebuthathaka?
Kalula nje, "ngumlawuli okrelekrele" wokufumanisa i-emission spectroscopy. Ngexesha lenkqubo yokufumanisa, akukho mfuneko yokungenelela ngesandla, kwaye inokufumana ngokuzenzekelayo imigca ye-spectral ngamandla afanelekileyo ngexesha langempela ngokusekelwe kuxinzelelo kunye nomxholo wento nganye, ifezekise umlinganiselo ochanekileyo ngaphandle kweziphene kulo lonke uluhlu. Nokuba luxinzelelo oluphantsi okanye oluphezulu, akukho mfuneko yokutshintsha imigca ye-spectral ngesandla. Isoftware inokuziqhelanisa ngokuzenzekelayo nesisombululo esifanelekileyo!
Inzuzo ephambili: Kutheni inokuba "ngukumkani osebenzayo"?
Ukugubungela okubanzi okubanzi: uxinzelelo oluphantsi luxhomekeke kwimigca eqinileyo ye-spectral ukuze kugcinwe uvakalelo, uxinzelelo oluphezulu luxhomekeke kwimigca ye-spectral ebuthathaka ukuze kugcinwe ulungelelwano, ngaphandle kwesidingo sokutshintsha iiparameter zokulinganisa okuninzi okanye ukutshintsha imigca ngesandla, okugubungela ngokulula lonke uluhlu loxinzelelo.
Ukuchasana nokugqwetheka: Ukubeka esweni imigca eqinileyo ye-spectral ngexesha langempela, xa umda ufikelele, itshintshela ngokuzenzekelayo kwimigca ye-spectral ebuthathaka, isombulula ngokupheleleyo ingxaki yokuphambuka komlinganiselo ophezulu.
Ukuchaneka akuchaphazeleki: Imigca ye-spectral eyomeleleyo nebuthathaka iyahambelana, igcina ukuchaneka okuphezulu kuhlalutyo oludibeneyo lwemigca ye-spectral emininzi.
Ifikelela njani "ekutshintsheni okukrelekrele"?
Ukuphunyezwa kwamanyathelo amabini okulungiswa ngokuzenzekelayo, umgaqo ulula kwaye kulula ukuwuqonda:
(1) Ukuhlala kunye kwee-curve ezininzi zokusebenza: Isoftware iqokelela ngaxeshanye imiqondiso emininzi yomgca we-spectral yohlalutyo lwento enye enamandla kunye nobuthathaka obahlukeneyo, kwaye ifanela i-curve yokusebenza yomgca ngamnye we-spectral. Misela nje umda wokuguqulwa ngokusekelwe kuluhlu oluchanekileyo lwe-curve nganye yokusebenza ukuze ugqibezele ukuhlelwa kwemigca ye-spectral enamandla/ebuthathaka.
(2) Ukutshintsha okuguquguqukayo: Okokuqala, sebenzisa imigca ye-spectral enamandla ukulawula umlinganiselo. Nje ukuba isiphumo sokufumanisa sifikelele kumda, siya kutshintshela ngokuzenzekelayo kwimigca ye-spectral ebuthathaka kwaye sitshintshele ngaphandle kokuphazamiseka kuyo yonke inkqubo.
Imizekelo yesicelo
Ekumiselweni kwesilivere (Ag), i-boron (B), i-tin (Sn), i-molybdenum (Mo), kunye ne-lead (Pb) kwiisampulu zomhlaba kunye ne-stream sediment kwishishini le-geological, iingenelo zokutshintsha ngokuzenzekelayo phakathi kwemigca eqinileyo nebuthathaka ziyafezekiswa ngokupheleleyo.
Kwimiba engaphantsi koxinzelelo, imigca eqinileyo—i-Ag (328.068 nm), i-Sn (317.50 nm), i-B (249.773 nm), i-Mo (313.2594 nm), kunye ne-Pb (283.3069 nm)—ibamba ngokuchanekileyo izinto ezilandelelanayo. Xa uxinano ludlula umda wokutshintsha umgca, inkqubo itshintshela ngokuzenzekelayo kwimigca ebuthathaka ukuze iphephe ukugcwala, kwaye inokwenza notshintsho oluninzi (umz., kwi-Pb). Ngohlalutyo oludibeneyo olusebenzisa imigca eqinileyo nebuthathaka, inkqubo ayihlangabezani neemfuno zokufumanisa kwinqanaba eliphantsi kuphela kodwa ikwagubungela uluhlu olufunekayo lokufumanisa iisampulu zomhlaba kunye nesediment yemilambo.
Ngamafutshane, ukutshintsha ngokuzenzekelayo phakathi kwemigca ye-spectral enamandla nebuthathaka ukuze kuhlalutywe imigca emininzi akufuneki kungenelelo lwesandla kwaye akukho zilingo zokuqala. Isombulula ngokulula iindawo ezibuhlungu ze-strong-line saturation kunye nengxolo ye-weak-line, ngelixa ilinganisa uvakalelo kunye nomgca-ukuphucula uhlalutyo lwe-spectrometric ukusuka "kwi-manual adaptation" ukuya "kwi-intelligence, operation engenamzamo."
