Inductively coupled plasma tandem mass spectrometry with CO gas reactions in a dynamic reaction cell almost eliminated the background noise intensity produced by isobaric interference from isotopes originating from actinides such as Am, Cm, and U at the locations (m/z) of significant Pu isotopes (Pu, Pu, Pu, Pu, and Pu).
