ISO 15202-3:2004 prescribes a procedure for the use of inductively coupled plasma atomic emission spectrometry for analysing test solutions prepared as prescribed in ISO 15202-2 from samples of airborne particulate matter collected as prescribed in ISO 15202-1. Method development, performance checks and a routine analysis method are prescribed.
The procedure suffers from no significant spectral interferences, provided that suitable analytical wavelengths are used. However, inaccurate background correction and/or inadequate matrix-matching can adversely affect results.
