Atomic Absorption Spectrometer (AAS)

Lub Atomic Absorption Spectrometer (AAS) yog ib lub cuab yeej siv los tshuaj xyuas cov ntsiab lus ntawm cov ntsiab lus los ntawm kev ntsuas qhov nqus ntawm lub teeb ntawm cov wavelengths tshwj xeeb los ntawm cov atoms hauv ib qho qauv. Cov qauv raug cua sov rau qhov kub siab, hloov nws cov ntsiab lus mus rau hauv daim ntawv roj atomic. Thaum lub teeb ntawm ib qho wavelength tshwj xeeb hla dhau cov qauv, cov atoms ntawm cov ntsiab lus nqus cov kab spectral uas resonate nrog lawv, tsim cov teeb liab nqus. AAS feem ntau yog siv rau kev tshuaj xyuas ntau ntawm cov ntsiab lus hlau, tshwj xeeb tshaj yog rau kev tshuaj xyuas cov hlau hnyav thiab cov ntsiab lus me me hauv dej zoo, kev saib xyuas ib puag ncig, khoom noj, tshuaj, thiab cov ntaub ntawv. Nws muaj kev rhiab heev, kev xaiv muaj zog, thiab yooj yim rau kev ua haujlwm, ua rau nws siv dav hauv kev saib xyuas ib puag ncig, kev tshuaj xyuas kev kho mob, kev tsim cov tshuaj lom neeg, thiab kev tswj xyuas zoo.
