I-Laser-Induced Breakdown Spectroscopy (LIBS), eyaziwa nangokuthi i-Laser-Induced Plasma Spectroscopy (LIPS), iyindlela yokuthola i-spectral esheshayo.
Ngokugxilisa i-laser pulse enomthamo omkhulu wamandla endaweni okuhloswe kuyo isampula ehloliwe, i-plasma ikhiqizwa ukuvuthwa kwe-ablation, bese ngokuhlaziya imigqa ye-spectral yesici ekhishwa ukuguqulwa kwezinga le-electron yezinhlayiya ze-plasma, izinhlobo nolwazi lokuqukethwe lwezakhi eziqukethwe kusampula lungatholakala.
Uma kuqhathaniswa nezindlela zokuthola izinto ezivame ukusetshenziswa ezisetshenziswa njengamanje, njenge-Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), i-Inductively coupled Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Ehlanganiswe I-PlasmaMass Spectrometer (ICP-XluRF) ), I-Spark Discharge Optical Emission Spectroscopy,SD-OES) Ngokufanayo, i-LIBS ayidingi ukulungiswa kwesampula, ingakwazi ukubona ngesikhathi esisodwa izakhi eziningi, ikwazi ukubona izimo eziqinile, eziwuketshezi, negesi, futhi ingahlolwa ukude futhi ku-inthanethi.
Ngakho-ke, selokhu kwaba khona ubuchwepheshe be-LIBS ngo-1963, budonse ukunaka okubanzi kwabacwaningi emazweni ahlukahlukene.Amandla okuthola ubuchwepheshe be-LIBS aboniswe izikhathi eziningi kuzilungiselelo zaselabhorethri.Kodwa-ke, endaweni yasensimini noma isimo sangempela sesizinda sezimboni, ubuchwepheshe be-LIBS budinga ukubeka phambili izidingo eziphakeme.
Isibonelo, uhlelo lwe-LIBS ngaphansi kweplathifomu ye-laboratory optical alunamandla kwezinye izimo lapho kunzima ukusampula noma ukuthutha amasampula ngenxa yamakhemikhali ayingozi, izinto ezikhipha imisebe noma ezinye izizathu, noma uma kunzima ukusebenzisa imishini yokuhlaziya enkulu endaweni encane. .
Kweminye imikhakha ethile, efana ne-archaeology yasendle, ukuhlola amaminerali, iziza zokukhiqiza zezimboni, ukutholwa kwesikhathi sangempela kubaluleke kakhulu, kanye nesidingo semishini yokuhlaziya ephathwayo emincane, ephathekayo.
Ngakho-ke, ukuze kuhlangatshezwane nezidingo zokusebenza kwensimu kanye nokutholwa kwe-inthanethi kokukhiqizwa kwezimboni kanye nokuhlukahluka kwezimpawu zesampula, ukuphatheka kwemishini, ikhono eliphikisana nemvelo eliqinile kanye nezinye izici ezintsha sekube yizidingo ezintsha neziphakeme zobuchwepheshe be-LIBS ekusetshenzisweni kwezimboni, i-LIBS ephathekayo. yaba khona, futhi iye yakhathazeka kakhulu abacwaningi emazweni ahlukahlukene.
