Abstract

A single collector double focusing sector field ICP-MS is evaluated for the determination of isotope ratios. Spectral interferences (e.g. 40Ar23Na on 63Cu) can lead to calculation of inaccurate ratios. The use of high resolution enables such interferences to be separated from the isotopes of interest. External reproducibilities of < 0.02% are shown for uninterfered isotopes (measured at low resolution R = 300) and < 0.1% for interfered isotopes which required the use of medium (R = 4000) and high resolution (R = 10000).
