内容記述 | In this work, a new 90Sr analysis method was developed using the Isotopx Ltd., Phoenix X62 thermal ionization mass spectrometer (TIMS). Excellent ion beam sensitivity was demonstrated with the detection of 1 mBq (0.2 fg) 90Sr on a Daly ion-counting system. The abundance sensitivity for the 90Sr/88Sr ratio was 2.1×10 10 and this could ensure measurement of 100 Bq·kg 1 (19 fg·g 1) 90Sr in an environmental sample with 100 µg·g 1 stable strontium concentration. For analytical method validation, 90Sr was determined in two certified reference materials e.g. wild berry (IRMM-426) and freshwater lake sediment (NIST-4354) for the first time in the history of TIMS. This mass spectrometry method is faster than conventional radiometric techniques; however, interference from 90Zr and peak tailing on the higher mass side from 88Sr must be considered for a reliable 90Sr determination. | |||||
