isoprime precisION stable isotope mass spectrometer

Measurement of natural variations in the abundances of stable isotopes of the same element is normally referred to as stable isotope analysis. This field is of interest because the differences in mass between different isotopes leads to isotope fractionation, causing measurable effects on the isotopic composition of samples, characteristic of their biological or physical history. http://web.gps.caltech.edu/~als/IRMS/course-materials/lecture-6---mass-analyzers/lecture-6-notes.pdf did dhoni retire from ipl
