spectroscopy mmebi nke laser kpatara

Laser-induced Breakdown Spectroscopy (LIBS), makwaara dị ka Laser-Induced Plasma Spectroscopy (LIPS), bụ usoro nchọpụta ngwa ngwa.

Site n'ilekwasị anya n'ụkwụ laser na njupụta ume dị elu n'elu ebumnuche nke nlele a nwalere, a na-emepụta plasma site na mkpali ablation, wee nyochaa njirimara spectral ahịrị na-egosipụta site na mgbanwe ọkwa ike elektrọn nke ihe ndị dị na plasma. Enwere ike nweta ụdị na ozi ọdịnaya nke ihe ndị dị na nlele ahụ.

E jiri ya tụnyere ụzọ nchọpụta mmewere nke a na-ejikarị ugbu a, dị ka Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), Plasmaoptical Mass Spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Ejikọtara PlasmaMass Spectrometer (ICP-MS), X-rayce (X-ray). ), Spark Discharge Optical Emission Spectroscopy, SD-OES) N'otu aka ahụ, LIBS anaghị achọ nkwadebe nlele, nwere ike ịchọpụta ọtụtụ ihe n'otu oge, nwere ike ịchọpụta ihe siri ike, mmiri mmiri na gas, ma nwee ike ịnwale ya na ntanetị.

Ya mere, kemgbe ọbịbịa nke teknụzụ LIBS na 1963, ọ dọtara mmasị dị ukwuu nke ndị nchọpụta na mba dị iche iche. Egosiputala ike nchọta teknụzụ LIBS ọtụtụ oge na Ntọala ụlọ nyocha. Otú ọ dị, na mpaghara ubi ma ọ bụ ọnọdụ n'ezie nke saịtị mmepụta ihe, nkà na ụzụ LIBS kwesịrị ịkwalite ihe ndị dị elu.

Dịka ọmụmaatụ, usoro LIBS n'okpuru ikpo okwu nyocha ụlọ nyocha enweghị ike n'ọnọdụ ụfọdụ mgbe ọ na-esiri ike ịlele ma ọ bụ bufee ihe nlele n'ihi kemịkalụ dị ize ndụ, ihe redioaktivu ma ọ bụ ihe ndị ọzọ, ma ọ bụ mgbe ọ siri ike iji nnukwu akụrụngwa nyocha na oghere dị warara. .

Maka mpaghara ụfọdụ akọwapụtara, dị ka nkà mmụta ihe ochie nke ubi, nchọpụta ịnweta ịnweta, saịtị mmepụta ihe, nchọpụta oge dị mkpa karịa, yana mkpa maka obere nyocha, ngwa nyocha.

Ya mere, iji gboo mkpa nke ọrụ ubi na mmepụta mmepụta ihe online nchọpụta na sample àgwà diversification, portability nke ngwá, mgbochi obi ike gburugburu ebe obibi na àgwà ọhụrụ ndị ọzọ aghọwo ọhụrụ na elu chọrọ maka LIBS technology na ulo oru ngwa, obere LIBS. malitere, ma ndị na-eme nchọpụta na mba dị iche iche na-enwe mmetụta nke ukwuu.
