I-Laser-induced breakdown spectroscopy

I-Laser-Induced Breakdown Spectroscopy (LIBS), ekwabizwa ngokuba yiLaser-Induced Plasma Spectroscopy (LIPS), yindlela yokukhangela ekhawulezayo yokubona.

Ngokugxininisa i-laser pulse kunye noxinano lwamandla aphezulu kumphezulu wethagethi yesampula evavanyiweyo, i-plasma iveliswa yi-excitation ye-ablation, kwaye emva koko ngokuhlalutya imigca ye-spectral yempawu esasazwa yi-electron level level transit of the particles in the plasma, iindidi kunye nolwazi lomxholo wezinto eziqulethwe kwisampuli zinokufumaneka.

Xa kuthelekiswa neendlela ezisetyenziswa ngoku eziqhelekileyo zokubona izinto, ezifana ne-Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), i-Inductively idityaniswe ne-Plasmaoptical mass spectrometry (I-Inductively Coupled PlasmaOptical Emission Spectrometry) Idityaniswe ne-PlasmaMass Spectrometer (ICP-FluRF) I-Emission Spectroscopy, SD-OES) Ngokufanayo, i-LIBS ayifuni ukulungiswa kwesampulu, inokubona ngaxeshanye izinto ezininzi, ikwazi ukubona izinto eziqinileyo, ezinolwelo kunye negesi, kwaye inokuvavanywa ukude nakwi-intanethi.

Ke ngoko, ukusukela oko kwavela itekhnoloji ye-LIBS ngo-1963, iye yatsala ingqalelo ebanzi yabaphandi kumazwe ahlukeneyo. Ubunakho bokubona ubuchwephesha be-LIBS bubonakaliswe amaxesha amaninzi kwiiSetingi zelabhoratri. Nangona kunjalo, kwindawo yentsimi okanye imeko yokwenyani yendawo yoshishino, itekhnoloji ye-LIBS kufuneka ibeke phambili iimfuno eziphezulu.

Ngokomzekelo, inkqubo ye-LIBS phantsi kwe-platform ye-laboratory optical ayinamandla kwezinye iimeko xa kunzima ukwenza isampuli okanye ukuthutha iisampulu ngenxa yeekhemikhali ezinobungozi, izinto ze-radioactive okanye ezinye izizathu, okanye xa kunzima ukusebenzisa izixhobo ezinkulu zokuhlalutya kwindawo emxinwa.

Kwezinye iinkalo ezithile, ezifana ne-archeology field, ukuhlola amaminerali, indawo yokuvelisa i-industrial, ukufumanisa ixesha langempela kubaluleke kakhulu, kunye nesidingo se-miniaturized, izixhobo zokuhlalutya eziphathekayo.

Ke ngoko, ukuze kuhlangatyezwane neemfuno zentsebenzo yentsimi kunye nemveliso yemveliso kwi-intanethi ubhaqo kunye neempawu zesampulu ezahlukeneyo, ukuphatheka kwezixhobo, amandla okusingqongileyo okuchasene noburhalarhume kunye nezinye iimpawu ezintsha ziye zaba ziimfuno ezintsha neziphakamileyo zetekhnoloji ye-LIBS kwizicelo zemizi-mveliso, i-LIBS ephathwayo yabakho, kwaye iye yaxhatshazwa ngokubanzi ngabaphandi kumazwe ahlukeneyo.
