Laser-Induced Breakdown Spectroscopy (LIBS), tseem hu ua Laser-Induced Plasma Spectroscopy (LIPS), yog cov txheej txheem ceev spectral nrhiav kom tau.
Los ntawm kev tsom mus rau lub laser pulse nrog lub zog siab ntom ntom, thiab tom qab ntawd los ntawm kev ntsuas hluav taws xob kev hloov pauv ntawm cov kab hluav taws xob ntawm cov nplais hauv lub Plasma, hom thiab cov ntsiab lus ntawm cov ntsiab lus muaj nyob hauv cov qauv tuaj yeem tau txais.
Piv nrog rau tam sim no siv cov txheej txheem tshawb nrhiav pom, xws li Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), Inductively coupled Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Coupled PlasmaMass Spectrometer (ICP-F-MS), ), Spark Discharge Optical Emission Spectroscopy, SD-OES) Ib yam li ntawd, LIBS tsis xav tau cov qauv kev npaj, tuaj yeem tshawb xyuas ntau lub ntsiab lus, tuaj yeem kuaj xyuas cov khoom, kua, thiab roj, thiab tuaj yeem kuaj tau nyob deb thiab hauv online.
Yog li ntawd, txij li thaum lub advent ntawm LIBS thev naus laus zis hauv xyoo 1963, nws tau nyiam cov neeg tshawb fawb thoob plaws hauv ntau lub tebchaws. Lub peev xwm tshawb pom ntawm LIBS thev naus laus zis tau pom ntau zaus hauv chav kuaj. Txawm li cas los xij, hauv thaj chaw ib puag ncig lossis qhov xwm txheej tiag tiag ntawm qhov chaw muaj kev lag luam, LIBS thev naus laus zis yuav tsum tau muab cov kev xav tau siab dua.
Piv txwv li, lub LIBS system nyob rau hauv lub chaw soj nstuam kho qhov muag platform yog tsis muaj hwj chim nyob rau hauv tej lub sij hawm thaum nws yog ib qho nyuaj rau coj mus kuaj los yog thauj cov qauv vim yog cov tshuaj txaus ntshai, radioactive tshuaj los yog lwm yam yog vim li cas, los yog thaum nws nyuaj rau siv loj analytical khoom nyob rau hauv ib tug nqaim qhov chaw. .
Rau qee qhov chaw tshwj xeeb, xws li kev tshawb nrhiav keeb kwm yav dhau los, kev tshawb nrhiav cov pob zeb hauv av, cov chaw tsim khoom lag luam, kev tshawb nrhiav lub sijhawm tiag tiag yog qhov tseem ceeb dua, thiab qhov xav tau ntawm cov khoom siv ntsuas me me, cov khoom siv txav tau yooj yim.
Yog li ntawd, txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua haujlwm thiab kev tsim khoom hauv online nrhiav pom thiab cov qauv kev sib txawv, cov khoom siv txav tau yooj yim, kev muaj peev xwm tiv thaiv ib puag ncig thiab lwm yam tshiab tau dhau los ua cov kev xav tau tshiab thiab siab dua rau LIBS thev naus laus zis hauv kev lag luam kev siv, portable LIBS. tau los ua, thiab tau muaj kev txhawj xeeb los ntawm cov kws tshawb fawb hauv ntau lub tebchaws.
