Laser-Induced Breakdown Spectroscopy (LIBS), eo hape e tsejoang e le Laser-Induced Plasma Spectroscopy (LIPS), ke mokhoa o potlakileng oa ho lemoha lipono.
Ka ho shebana le sekhahla sa laser se nang le matla a phahameng a matla holim'a sepheo sa sampole e lekiloeng, plasma e hlahisoa ke ho hlasimoloha ha moea, ebe ka ho sekaseka mela e ikhethang e hlahisoang ke phetoho ea matla a elektronike ea likaroloana tsa plasma. mefuta le tlhahisoleseding ea litaba tsa likarolo tse fupereng mohlala li ka fumanoa.
Ha ho bapisoa le mekhoa e sebelisoang hona joale ea ho lemoha lintho, e kang Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), Inductively Couple Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Coupled PlasmaMass Spectrometer (ICP-FluRF) ), Spark Discharge Optical Emission Spectroscopy,SD-OES) Ka mokhoa o ts'oanang, LIBS ha e hloke ho lokisoa ha sampuli, e ka khona ho lemoha lintho tse ngata ka nako e le 'ngoe, e khona ho lemoha libaka tse tiileng, tsa metsi le tsa khase,' me e ka lekoa ka thōko le inthaneteng.
Ka hona, ho tloha ha theknoloji ea LIBS e qala ka 1963, e hohetse tlhokomelo e kholo ea bafuputsi linaheng tse fapaneng. Bokhoni ba ho lemoha ba theknoloji ea LIBS bo bontšitsoe hangata ho Litlhophiso tsa laboratori. Leha ho le joalo, tikolohong ea tšimo kapa boemo ba 'nete ba sebaka sa indasteri, theknoloji ea LIBS e hloka ho beha litlhoko tse holimo.
Ka mohlala, tsamaiso ea LIBS tlas'a sethala sa laboratory optical ha e na matla maemong a mang ha ho le thata ho etsa sampole kapa ho tsamaisa lisampole ka lebaka la lik'hemik'hale tse kotsi, lintho tse nang le mahlaseli a kotsi kapa mabaka a mang, kapa ha ho le thata ho sebelisa lisebelisoa tse kholo tsa tlhahlobo sebakeng se moqotetsane. .
Bakeng sa likarolo tse ling tse khethehileng, tse kang ho epolloa ha lintho tsa khale, ho hlahloba liminerale, libaka tsa tlhahiso ea indasteri, ho lemoha nako ea sebele ho bohlokoa haholo, le tlhokahalo ea lisebelisoa tsa ho hlahloba tse nyenyane, tse nkehang habonolo.
Ka hona, e le ho fihlela litlhoko tsa ts'ebetso ea ts'ebetso ea ts'ebetso le tlhahiso ea liindasteri tse fumanehang marang-rang le ho fapanyetsana ha litšoaneleho tsa sampole, ts'ebeliso ea lisebelisoa, bokhoni bo khahlano le tikoloho le litšobotsi tse ling tse ncha li fetohile litlhoko tse ncha le tse phahameng tsa theknoloji ea LIBS lits'ebetsong tsa indasteri, LIBS tse nkehang. e bile teng, ’me e ’nile ea tšoenngoa haholo ke bafuputsi linaheng tse sa tšoaneng.
