I-Laser-Induced Breakdown Spectroscopy (LIBS), eyaziwa ngokuba yi-Laser-Induced Plasma Spectroscopy (LIPS), yindlela yokubona ngokukhawuleza ii-spectral.
Ngokujolisa i-laser pulse enobuninzi bamandla kumphezulu wethagethi yesampuli evavanyiweyo, i-plasma iveliswa yi-ablation excitation, kwaye emva koko ngokuhlalutya imigca ye-spectral ephawulekayo ekhutshwa kukutshintsha kwenqanaba lamandla e-electron lamasuntswana kwi-plasma, iintlobo kunye nolwazi lomxholo wezinto ezikwisampuli zinokufunyanwa.
Xa kuthelekiswa neendlela zokufumanisa izinto ezisetyenziswa rhoqo ngoku, ezifana ne-Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), i-Inductively coupled Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) i-Coupled PlasmaMass Spectrometer (ICP-MS), i-X-ray Fluorescence (XRF), i-Spark Discharge Optical Emission Spectroscopy, i-SD-OES) Ngokufanayo, i-LIBS ayifuni ukulungiswa kwesampulu, inokubona izinto ezininzi ngaxeshanye, inokubona imeko eqinileyo, yolwelo, kunye neyegesi, kwaye inokuvavanywa kude nakwi-intanethi.
Ngoko ke, ukusukela oko kwaqala iteknoloji ye-LIBS ngo-1963, itsale ingqalelo enkulu yabaphandi kumazwe ahlukeneyo. Amandla okufumanisa iteknoloji ye-LIBS abonakaliswe amaxesha amaninzi kwiindawo zelebhu. Nangona kunjalo, kwimeko yentsimi okanye kwimeko yokwenyani yendawo yemizi-mveliso, iteknoloji ye-LIBS kufuneka ibeke phambili iimfuno eziphezulu.
Umzekelo, inkqubo ye-LIBS phantsi kweqonga le-optical lelebhu ayinamandla kwezinye iimeko xa kunzima ukusampula okanye ukuthutha iisampulu ngenxa yeekhemikhali eziyingozi, izinto ezinemisebe okanye ezinye izizathu, okanye xa kunzima ukusebenzisa izixhobo ezinkulu zohlalutyo kwindawo emxinwa.
Kweminye imimandla ethile, efana nophando lwezinto zakudala, uphando lwezimbiwa, iindawo zemveliso yemizi-mveliso, ukufunyanwa kwexesha langempela kubaluleke ngakumbi, kunye nesidingo sezixhobo zohlalutyo ezincinci neziphathekayo.
Ke ngoko, ukuze kuhlangatyezwane neemfuno zemisebenzi yasentsimini kunye nokufunyanwa kwemveliso kwi-intanethi kunye nokwahlukahluka kweempawu zeesampuli, ukuthwalwa kwezixhobo, amandla okusingqongileyo okuchasene nobunzima kunye nezinye iimpawu ezintsha ziye zaba ziimfuno ezintsha neziphezulu zobuchwepheshe be-LIBS kwizicelo zoshishino, i-LIBS ephathekayo yavela, kwaye iye yaxhalatyiswa kakhulu ngabaphandi kumazwe ahlukeneyo.
