Ha. Furusawa et al., Uranium isotopic analyses by using a sector field inductively coupled plasma mass spectrometer, J RAD NUCL, 242(3), 1999, pp. 647-651
A sector field mass spectrometer using an inductively coupled plasma as an
ion source was used in order to determine the uranium isotopic ratios in re
ference materials supplied by the National Institute of Standards and Techn
ology (NIST) (NBS 950, 010, 030, 200, 500, 750, and 970). The accuracy obta
ined for the major isotopes was better than 0.2%.
