Background Correction in AAS Absorption by the flame atomizer itself as well as by concomitants introduced into the flame or electrothermal atomizer can cause serious problems in AAS. Rarely are there interferences from absorption of the analyte line by other atoms since the HCL lines are so narrow....

Background Correction In Aas Pdf
Perfect background correction (BC) can be obtained only when the background absorbance measurement corresponds exactly in space, time, and wavelength with the atomic absorbance measurement. Since exact coincidence of all three parameters is obviously impossible, it is customary to give priority to the equality in space and to make the difference in time and/or wavelength as small …
