Uranium Isotope Ratio Measurements with the NexION ICP-MS

One of the beneficial features of inductively coupled mass spectrometry (ICP-MS) is its ability to measure multiple isotopes of the same element. This ability is useful in many analyses, primarily as confirmation of a correct answer (i.e. if two isotopes of the same element give the same result, the result is most likely correct) or the ability to select another analytical isotope, if an interference exists on the desired isotope.
