Since unique elements have characteristic (signature) spectras, atomic spectroscopy, specifically the electromagnetic spectrum or mass spectrum, is applied for determination of elemental compositions. It can be divided by atomization source or by the type of spectroscopy used.  In the latter case, the main division is between optical and mass spectrometry."] } } }
