Abstract
- Pu isotopes in various foods were detected using a quadrupole ICPMS and Aridus II desolvation nebulizer. The method has ability to detect 239 Pu and 240 Pu at concentrations of ~52 pg/kg (0.12 Bq/kg) and ~9.5 pg/kg (0.08 Bq/kg) as well as 240 Pu/ 239 Pu ratio in <8 h after receiving the samples. Foods were wet-ashed followed by DGA extraction for eliminating matrix, isobaric, and polyatomic interferences. A UH + formation rate <10 −5 and a 5-fold enhanced sensitivity for Pu was achieved after system optimization. [ABSTRACT FROM AUTHOR]
