Times Cited Count:4 Percentile:36.57(Chemistry, Analytical)The determination of a low concentration of Sr was achieved by the combination of online SPE-ICP-QMS and ID method using
Sr/
Sr ratio. No requirement of radioactive standard material and the preparation process of the calibration curve was in the quantification process and data acquisition can be in one-shot sample injection. The proposed method allowed the rapid (within 15 min/sample) quantification of
Sr in the presence of significant interferences such as isobaric
Zr and other elements. The LOD for
Sr was 5.6 Bq/L for a 10 mL injection and this could be improved by simply increasing the sample volume injected.
