Kusanthula kwa laser-induced breakdown spectroscopy

Laser-Induced Breakdown Spectroscopy (LIBS), yomwe imadziwikanso kuti Laser-Induced Plasma Spectroscopy (LIPS), ndi njira yodziwira mwachangu ma spectral.

Mwa kuyang'ana kugunda kwa laser ndi mphamvu zambiri pamwamba pa cholinga cha chitsanzo choyesedwa, plasma imapangidwa ndi ablation excitation, kenako pofufuza mizere ya spectral yomwe imatulutsidwa ndi kusintha kwa mphamvu ya ma electron ya tinthu tating'onoting'ono mu plasma, mitundu ndi zambiri za zinthu zomwe zili mu chitsanzocho zingapezeke.

Poyerekeza ndi njira zodziwira zinthu zomwe zimagwiritsidwa ntchito kwambiri masiku ano, monga Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), Inductively coupled Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Coupled PlasmaMass Spectrometer (ICP-MS), X-ray Fluorescence (XRF), Spark Discharge Optical Emission Spectroscopy, SD-OES) Mofananamo, LIBS siifuna kukonzekera zitsanzo, imatha kuzindikira zinthu zingapo nthawi imodzi, imatha kuzindikira momwe zinthu zilili zolimba, zamadzimadzi, ndi mpweya, ndipo imatha kuyesedwa patali komanso pa intaneti.

Chifukwa chake, kuyambira pomwe ukadaulo wa LIBS unayamba mu 1963, wakopa chidwi cha ofufuza ambiri m'maiko osiyanasiyana. Mphamvu zopezera ukadaulo wa LIBS zawonetsedwa kangapo m'malo oyesera. Komabe, m'malo ogwirira ntchito kapena momwe zinthu zilili pamalo enieni a mafakitale, ukadaulo wa LIBS uyenera kupereka zofunikira zapamwamba.

Mwachitsanzo, dongosolo la LIBS pansi pa nsanja ya optical ya labotale siligwira ntchito nthawi zina pamene zimakhala zovuta kuyesa kapena kunyamula zitsanzo chifukwa cha mankhwala oopsa, zinthu zowononga mphamvu kapena zifukwa zina, kapena pamene zimakhala zovuta kugwiritsa ntchito zida zazikulu zowunikira pamalo ochepa.

Pazinthu zina zapadera, monga kafukufuku wa zinthu zakale m'munda, kufufuza miyala, malo opangira mafakitale, kuzindikira nthawi yeniyeni ndikofunikira kwambiri, komanso kufunikira kwa zida zazing'ono zowunikira zomwe zimanyamulika.

Chifukwa chake, kuti akwaniritse zosowa za ntchito zam'munda ndi kupanga mafakitale pa intaneti komanso kuzindikira mitundu yosiyanasiyana ya zitsanzo, kusunthika kwa zida, kuthekera kolimbana ndi zovuta zachilengedwe ndi makhalidwe ena atsopano kwakhala zofunikira zatsopano komanso zapamwamba paukadaulo wa LIBS mu ntchito zamafakitale, LIBS yonyamulika idayamba, ndipo yakhala ikudetsa nkhawa kwambiri ndi ofufuza m'maiko osiyanasiyana.
