Kana zvasvika kuma spectrometer emission atomic, vanhu vazhinji vanobva vangofunga nezve ICP-AES kana kuti pamwe ma spectrometer e spark direct-reading. Vashoma vanotaura nezve arc emission spectrometers. Asi, semunhu agara ari nhengo yemhuri yema spectrometer emission atomic, tekinoroji iyi yakaita mipiro mikuru mumakumi emakore apfuura mukuongorora kwemhando uye huwandu hwezvinhu zvisingararami muminda yakaita sekuongorora geology, simbi dzisina ferrous, nesainzi yezvinhu.
Kunyangwe nanhasi, nemidziyo yepamusoro-soro iripo, zvakanakira zvayo—sekuongorora zvakananga sampuro dzeupfu uye kunzwa kwakanyanya—zvakaita kuti irambe iri nzira yakatarwa yekuona sirivha, boron, uye tin muindasitiri yezve geology. Ichiri chishandiso chakakosha muma laboratories ezve geology uye ndiyo nzira inokurudzirwa yekuona zvinhu zvisina kuchena musimbi dzakachena zvakanyanya senge tungsten, molybdenum, niobium, uye tantalum, pamwe chete nema oxides adzo.
Iyo classic spectrograph iri kukura zvakanyanya
Kutanga, ngatizivei nezve "veterans" ve arc emission spectrometry. Ma arc atomic spectrometer ekutanga aishandisa ma photographic plates kutora emission spectra uye ainzi ma spectrographs. Nyaya iyi yakatanga muna 1969 apo Beijing Beifen Ruili Analytical Instruments (Group) Co., Ltd.—Beijing Nhamba 2 Optical Instrument Factory—yakagadzira zvinobudirira plane grating spectrograph ine mita imwe chete. Modhi iyi ichiri kuonekwa mumarabhoritari mazhinji nhasi.
Spektrogirafu yemita imwe
Chishandiso ichi chaive chakaita se "darkroom master" ine hungwaru. Kunyangwe chaive chakaoma kushandisa (chichida matanho ekugadzirisa mapikicha), kunzwisisika kwacho kwakanyanya ndiko kwakaisa hwaro hwekuongorora maspectral e arc uye chaive chisingatsiviwi panguva iyoyo. Ungave wakaonawo mamodheru makuru—ma spectrograph e grating ane mamita maviri ane "barrel" hombe yegirinhi.

"Bhara guru" re "focal barrel" rakakura mamita maviri rinoshamisa sei? Zvino, tarisai dombo guru iri riri pazasi. Rinonzi rine focal barrel yakareba mamita 3.4, iyo isingakodzeri kurobhoritari yakajairika, uye rinewo mwenje mukuru unobatsira kuburitsa chiedza.

Maitiro Ekuwana Data Rakaoma
Kuwana data kubva ku spectrograph kwaive chinhu chinonetesa uye chakaoma: mushure mekugadzirira sampuro, spectrograph yaiitwa. Kana yapera, chibatiso cheplate chemifananidzo chaifanira kubviswa choendeswa kuimba yerima. Pasi pechiedza chitsvuku chisina kujeka, plate yacho yaigadzirwa, yaigadziriswa, uye yaisukwa—maitiro akafanana nekugadzira mapikicha matema nemachena.
Purati yakagadziriswa zvakanaka inogona kubuda yakasviba zvachose nekuda kwekunyanya kusviba, zvichiita kuti basa rese rekare risashande. Neimwe nzira, nekuda kwematambudziko nemugadziri kana mugadziri, purati inogona kunge yakasviba zvakanyanya kana kuti yakareruka zvekuti haigone kushandiswa, zvichiita kuti itangezve kushanda.
Imba yerima
Nekuda kwekuwanda kwemitsetse yespectral inobuda, waifanira kuiongorora uchishandisa kukura kwakanyanya, uchisarudza mitsetse yekuongorora yechinhu chimwe nechimwe chaunoda chimwe nechimwe. Kuongorora huwandu kwaida kuyera density yavo uchishandisa densitometer. Kunyangwe kune vanoongorora vane ruzivo, izvi zvaive zvisiri nyore; kune vatsva, zvaive zvinotyisa. Maziso akaomeswa nekutarisa mitsetse, asi mitsetse mishoma chete ndiyo yakawanikwa.
MaSensor Emifananidzo Anotsiva Mapuleti Emifananidzo
Nekufambira mberi kwetekinoroji, tekinoroji yekunzwa mifananidzo yakakura uye yakawana mashandisirwo mumaindasitiri akasiyana-siyana. Kungofanana nemakamera edhijitari akatsiva makamera efirimu, masensa emifananidzo akachinja arc emission spectrometry nekutsiva mapicture emifananidzo echinyakare. Vachishandisa photoelectric effect, masensa aya anoshandura masaini emaziso kuita masaini emagetsi, vachizopedzisira vaaita digitally kuti aonekwe zvakananga pakombiyuta—zvichibvisa maitiro akaoma ekuwana data rema spectrograph echinyakare.
Chinjo chaiyo yakaitika pakati pa2011 na2014.BFRLYakatanga AES-7000 series—chinhu chitsva chakabatanidza arc source spectral analysis nema photomultiplier tubes (PMTs) kuti vawane "kuverenga zvakananga." Vashandisi vakazopedzisira vasunungurwa kubva pamatanho anodiwa nesimba akadai sekugadzirisa maplate uye kuyerwa kwehuwandu hwevanhu, zvichivandudza kushanda zvakanaka uye kukurumidzisa kushandiswa kwetekinoroji iyi mu geology ne metallurgy.
Kunyange zvazvo AES-7000 series yaive nekukurumidza, yaive nemiganhu—mitsara yayo yespectral yakagadziriswa. Muna 2017,BFRLYakatora danho rimwe mberi nekuburitswa kwepamutemo kwe spectrometer yechizvarwa chinotevera, AES-8000. Chishandiso ichi chakagara nhaka simba re spectrographs dzechinyakare dzemita imwe chete—alternating current/direct current (AC/DC) arc excitation, three-lens illumination system, uye nzira yekare yeEbert-Fassie optical—ukuwo ichishandisa sensor yeCMOS inoshanda zvakanyanya yekuona masaini. Yakagadziridzwa zvizere, yakawana danho kubva "pakuziva kuti iripo" kuenda "pakuona zvese." Zviri nyore kushandisa, nekukurumidza, uye zviri nyore, AES-8000 yakagadzirisa zvakananga marwadzo evashandisi ve spectrograph uye yakakurumidza kuva chigadzirwa chikuru muchizvarwa chitsva che arc emission spectrometers.
✔ Kubudirira Pakushanda: Kushandiswa kwemusanganiswa we "Ebert-Fassie optical system + CMOS detector". Kunzwa kweCMOS kwakapetwa kakawanda kupfuura kweCCD dzakajairika, uye pamwe chete ne patented optics, kupindirana kwemashure kunoderedzwa.
✔ Kugadzira Zvinhu Zvitsva: Kuongorora kwakazara kwezvinhu. Hazvina kungogadzirisa dambudziko reindasitiri rekuyera zvinhu nemazvo zvakaita sesirivha, tin, uye boron mumienzaniso yejiyoroji chete asiwo zvakazadzisa zvinodiwa nemazvo zvemitemo yenyika.
✔ Ruzivo Rwakangwara: Kurongeka kwema electrode otomatiki, kuvharira kwakachengeteka, kugadzirisa kumashure kwesoftware otomatiki—zvinhu izvi zvine hungwaru zvinoita kuti chishandiso chisangova chakanyatsojeka chete asiwo chive "chinoshandisika" uye chakachengeteka.
