Flame atomic absorption

WebNov 1, 2010 · The sample must be in liquid form for analysis by flame atomic absorption. If there are particulates in solution which contain the analyte, these particulates may settle out and give an absorbance much lower than the true value would be. Small particles (less than 10 ,am) can be analyzed by flame AA but large ones may not be com- pletely atomized. WebAtomic absorption spectroscopy uses light in the ultraviolet-visible range. For Pb analysis, a thin beam of light is passed through the flame containing the analyte. The beam contains light at 283.3 nm. The light is absorbed by Pb atoms as excitation of electrons from the …
