• The effects of organic solvents on the sensitivity of atomic absorption spectrometry were investigated by using iron and magnesium as examples. The sensitivity increased remarkably when organic solvent was added to the sample solution. To clarify this effect, the feeding rates of sample solution into atomizer chamber and into flame were measured. The former rate was lower in the case of mixed solvent than aqueous solution, but the latter one was almost the same in both cases, because the atomization efficiency was greater when organic solvent was added to the sample solution. From these observations, the increase in sensitivity can be explained by the fact that the size of spray droplets is smaller when mixed solvent is used, and that species in droplets can be effectively dissociated into atomic state in flame.
