Mass-shift mode to quantify low level¹²⁹I in environmental samples by ICP-MS/MS

Abstract

In this study, a new measurement method to quantify 129I at low level by ICP-MS/MS (Agilent 8900) was developed. This new method is based on a new measurement medium and...

“…Using 97 Tc as a yield tracer for 99 Tc, the absolute LOD was 0.9 fg (0.6 mBq). In a similar procedure, the 129 Xe + isobaric interference on 129 I + decreased 93 substantially when I was reacted with O 2 and measured as 129 I 16 O + at m / z 145. In this way a LOD of 11 mBq L −1 was achieved without the need for any sample pretreatment.…”
