A small amount of ⁹⁰Sr in environmental samples are able to be detected by inductively coupled plasma mass spectrometry with online solid phase extraction. However, signal intensity and recovery yield are decreased by matrices such as Ca, which are contained in samples. In this presentation, a suitable method is described.
