To fully utilize the potential of volatile species generation the atomization step has to be optimized. Currently, the optimization is typically performed on the purely trial and error basis. The reason is that atomization of volatile species in the most often employed atomizers, quartz tubes and flames, proceeds via analyte interaction with hydrogen radicals which are extremely difficult to detect even though they are present in these atomizers at concentration several orders of magnitude above the equilibrium. There were attempts to prove hydrogen radical presence in quartz tube atomizers but no conclusive results were found because of the extreme complexity of employed techniques.
