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 chemuenzaniso wakaedzwa, plasma inogadzirwa neablation excitation, uyezve nekuongorora hunhu hwema spectral mitsara inovhenekerwa neelectron energy level shanduko yezvimedu muplasma, mhando uye ruzivo rwezvirimo 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-rayFluRF) Xres Emission Spectroscopy, SD-OES) Saizvozvo, LIBS haidi gadziriro yemuenzaniso, inogona kuona panguva imwe chete zvinhu zvakawanda, inogona kuona yakasimba, mvura, uye gasi nyika, uye inogona kuedzwa 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.

Semuenzaniso, iyo LIBS sisitimu iri pasi perabhoritari optical papuratifomu haina simba mune dzimwe nguva kana zvichinetsa kusampula kana kutakura sampuli nekuda kwekemikari ine njodzi, radioactive zvinhu kana zvimwe zvikonzero, kana kana zvakaoma kushandisa hombe yekuongorora michina munzvimbo yakamanikana.

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, kuti zvizadzise zvinodikanwa zvekushanda kwemumunda uye kugadzirwa kwemaindasitiri pamhepo kuona uye sampuli hunhu hwekusiyanisa, kutakurika kwemidziyo, anti-hasha nharaunda kugona uye humwe hunhu hutsva hwava hutsva uye hwepamusoro zvinodiwa zveLIBS tekinoroji mumaindasitiri maapplication, inotakurika LIBS yakatanga, uye yave ichinetsekana zvakanyanya nevaongorori munyika dzakasiyana siyana.
