Laser-induced breakdown spectroscopy

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

Poyang'ana kugunda kwa laser ndi kachulukidwe wamkulu wa mphamvu pamwamba pa chandamale cha chitsanzo choyesedwa, madzi a m'magazi amapangidwa ndi chisangalalo cha ablation, ndiyeno posanthula mizere yowoneka bwino yowulutsidwa ndi kusintha kwa ma elekitironi amphamvu ya particles mu plasma, mitundu ndi zomwe zili muzinthu zomwe zili mu chitsanzo zitha kupezeka.

Poyerekeza ndi njira zomwe zimagwiritsidwa ntchito masiku ano, monga Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), Inductively Couple Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Coupled PlasmaMass Spectrometer (ICP-FluRF) ), Spark Discharge Optical Emission Spectroscopy,SD-OES) Mofananamo, LIBS sichifuna kukonzekera kwachitsanzo, imatha kuzindikira nthawi imodzi zinthu zingapo, imatha kuzindikira zolimba, zamadzimadzi, ndi mpweya, ndipo zimatha kuyesedwa patali komanso pa intaneti.

Chifukwa chake, kuyambira ukadaulo wa LIBS ku 1963, wakopa chidwi cha ofufuza m'maiko osiyanasiyana. Kuthekera kozindikira kwaukadaulo wa LIBS kwawonetsedwa nthawi zambiri muzokonda za labotale. Komabe, m'malo am'munda kapena momwe malo amagwirira ntchito, ukadaulo wa LIBS uyenera kuyika patsogolo zofunikira.

Mwachitsanzo, dongosolo la LIBS pansi pa nsanja ya labotale silikhala ndi mphamvu nthawi zina pamene zimakhala zovuta kuyesa kapena kunyamula zitsanzo chifukwa cha mankhwala oopsa, zinthu zowononga ma radio kapena zifukwa zina, kapena pamene kuli kovuta kugwiritsa ntchito zida zazikulu zowunikira pamalo opapatiza. .

Kwa madera ena apadera, monga kufukufuku wa m'munda, kufufuza mchere, malo opangira mafakitale, kufufuza nthawi yeniyeni ndikofunikira kwambiri, komanso kufunikira kwa zida zowunikira zazing'ono, zonyamula.

Choncho, pofuna kukwaniritsa zosowa za ntchito kumunda ndi kupanga mafakitale kudziwika pa Intaneti ndi zitsanzo makhalidwe osiyanasiyana, kunyamula zida, odana ndi nkhanza chilengedwe mphamvu ndi makhalidwe ena atsopano akhala zatsopano ndi apamwamba zofunika LIBS luso mu ntchito mafakitale, kunyamula LIBS zinakhalapo, ndipo zakhudzidwa kwambiri ndi ofufuza m'mayiko osiyanasiyana.
