Laser-induced breakdown spectroscopy

Laser-Induced Breakdown Spectroscopy (LIBS), inozivikanwawo seLaser-Induced Plasma Spectroscopy (LIPS), inokurumidza spectral yekuona maitiro.

Nekutarisisa iyo laser pulse ine yakakwira simba density pamusoro pechinangwa cheiyo yakaedzwa sampu, iyo plasma inogadzirwa neablation excitation, uyezve nekuongorora hunhu hwema spectral mitsara inovhenekerwa neiyo electron simba level shanduko yezvikamu zviri muplasma, mhando uye ruzivo rwezvinyorwa zvezvinhu zviri mumuenzaniso zvinogona kuwanikwa.

Zvichienzaniswa neazvino anowanzo shandiswa ekuona zvinhu nzira, dzakadai seInductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), Inductively yakasanganiswa Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Yakabatanidzwa PlasmaMass Spectrometer (ICP-FluRF) ), Spark Discharge Optical Emission Spectroscopy,SD-OES) Saizvozvo, LIBS haidi kugadzirira sampuli, inogona kuona panguva imwe chete zvinhu zvakawanda, inogona kuona yakasimba, mvura, uye gasi nyika, uye inogona kuongororwa kure uye online.

Naizvozvo, kubvira pakatanga tekinoroji yeLIBS muna 1963, yakwezva kutarisisa kwevaongorori munyika dzakasiyana siyana. Iko kugona kwekuona kweLIBS tekinoroji kwakaratidzwa kakawanda muLabhoritari Settings. Nekudaro, munzvimbo yemunda kana mamiriro chaiwo eiyo saiti yemaindasitiri, tekinoroji yeLIBS inoda kuisa mberi kwepamusoro zvinodiwa.

Semuyenzaniso, iyo LIBS sisitimu iri pasi perabhoritari optical chikuva haina simba mune dzimwe nguva kana zvichinetsa kuenzanisa kana kutakura sampuli nekuda kwekemikari ine njodzi, zvinhu zvine radioactive kana zvimwe zvikonzero, kana pazvinenge zvakaoma kushandisa midziyo yakakura yekuongorora munzvimbo nhete. .

Kune mamwe minda chaiyo, senge munda wekuchera matongo, kuongororwa kwemaminerari, nzvimbo dzekugadzira maindasitiri, kuona-nguva chaiyo kunonyanya kukosha, uye kudiwa kweminiaturized, inotakurika yekuongorora michina.

Naizvozvo, kuitira kuzadzisa zvinodikanwa zvekushanda kwemumunda uye kugadzirwa kwemaindasitiri pamhepo kuona uye sampuli hunhu hwekusiyanisa, kutakurika kwemidziyo, anti-hasha nharaunda kugona uye humwe hunhu hutsva hwave hutsva uye hwepamusoro zvinodiwa zveLIBS tekinoroji mumaindasitiri maapplication, inotakurika LIBS. yakavapo, uye yave ichinetseka zvakanyanya nevatsvakurudzi munyika dzakasiyana-siyana.
