Laser-Induced Breakdown Spectroscopy (LIBS), tseem hu ua Laser-Induced Plasma Spectroscopy (LIPS), yog ib txoj kev kuaj pom spectral ceev.
Los ntawm kev tsom mus rau lub laser pulse nrog lub zog siab ceev ntawm qhov chaw ntawm lub hom phiaj ntawm cov qauv kuaj, cov plasma yog tsim los ntawm ablation excitation, thiab tom qab ntawd los ntawm kev tshuaj xyuas cov kab spectral yam ntxwv uas tau tawg los ntawm kev hloov pauv ntawm lub zog hluav taws xob ntawm cov khoom me me hauv cov plasma, cov hom thiab cov ntsiab lus ntawm cov ntsiab lus muaj nyob hauv cov qauv tuaj yeem tau txais.
Piv nrog rau cov txheej txheem nrhiav cov khoom siv tam sim no, xws li Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), Inductively coupled Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Coupled PlasmaMass Spectrometer (ICP-MS), X-ray Fluorescence (XRF), Spark Discharge Optical Emission Spectroscopy,SD-OES) Ib yam li ntawd, LIBS tsis tas yuav npaj cov qauv, tuaj yeem ntes tau ntau yam khoom tib lub sijhawm, tuaj yeem ntes tau cov khoom khov, kua, thiab roj, thiab tuaj yeem sim ua haujlwm deb thiab online.
Yog li ntawd, txij li thaum muaj thev naus laus zis LIBS xyoo 1963, nws tau nyiam cov kws tshawb fawb hauv ntau lub tebchaws. Lub peev xwm nrhiav tau ntawm thev naus laus zis LIBS tau pom ntau zaus hauv chaw kuaj mob. Txawm li cas los xij, hauv thaj chaw lossis qhov xwm txheej tiag tiag ntawm qhov chaw lag luam, thev naus laus zis LIBS yuav tsum tau muab cov kev xav tau siab dua.
Piv txwv li, lub LIBS system nyob rau hauv lub chaw kuaj mob optical platform tsis muaj zog hauv qee kis thaum nws nyuaj rau kuaj lossis thauj cov qauv vim muaj cov tshuaj lom neeg txaus ntshai, cov tshuaj radioactive lossis lwm yam laj thawj, lossis thaum nws nyuaj rau siv cov khoom siv tshuaj ntsuam loj hauv qhov chaw nqaim.
Rau qee qhov chaw tshwj xeeb, xws li kev tshawb nrhiav txog keeb kwm yav dhau los, kev tshawb nrhiav cov khoom siv hauv av, cov chaw tsim khoom lag luam, kev tshawb pom tiag tiag yog qhov tseem ceeb dua, thiab qhov xav tau cov khoom siv me me, cov khoom siv tshuaj ntsuam xyuas tau yooj yim.
Yog li ntawd, txhawm rau kom ua tau raws li qhov xav tau ntawm kev ua haujlwm hauv thaj teb thiab kev tsim khoom hauv kev lag luam hauv online thiab kev sib txawv ntawm cov yam ntxwv ntawm cov qauv, kev yooj yim nqa khoom siv, kev tiv thaiv ib puag ncig tsis zoo thiab lwm yam ntxwv tshiab tau dhau los ua qhov tshiab thiab siab dua rau LIBS thev naus laus zis hauv kev siv hauv kev lag luam, portable LIBS tau los ua, thiab tau txais kev txhawj xeeb dav los ntawm cov kws tshawb fawb hauv ntau lub tebchaws.
