【 摘 要 】

The collision/reaction interface with He introduced through the skimmer at 100 mL min-1 is employed to improve accuracy in 31P+ determinations by ICP-QMS. The 31P16O+ determination in cool plasma conditions result in limits of detection 55-fold lower. This strategy may be an interesting alternative for high ionization potential elements such as P.
