Atomic Absorption Spectrometer (AAS)

Atomic Absorption Spectrometer (AAS) ndi chida chomwe chimagwiritsidwa ntchito pofufuza zomwe zili mu zinthu poyesa kuyamwa kwa kuwala pa mafunde enaake ndi maatomu mu chitsanzo. Chitsanzocho chimatenthedwa mpaka kutentha kwambiri, kusintha zinthu zake kukhala mpweya wa atomu. Pamene kuwala kwa mafunde enaake kumadutsa mu chitsanzocho, maatomu a zinthuzo amayamwa mizere ya spectral yomwe imalumikizana nawo, ndikupanga chizindikiro choyamwa. AAS imagwiritsidwa ntchito makamaka pofufuza kuchuluka kwa zinthu zachitsulo, makamaka pakuwunika zitsulo zolemera ndi zinthu zochepa mu ubwino wa madzi, kuyang'anira chilengedwe, chakudya, mankhwala, ndi zipangizo. Imapereka kukhudzidwa kwakukulu, kusankha kwamphamvu, komanso kosavuta kugwiritsa ntchito, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri poyang'anira chilengedwe, kusanthula zachipatala, kupanga mankhwala, ndi kuwongolera khalidwe.
