Optimal sample to tracer ratio for Isotope Mass Spectrometry : the polyisotopic case
The isotope dilution mass spectrometry measurement technique provides a means for determining the unknown amount of various isotopes of an element in a sample solution of known mass. The sample solution is mixed with an auxiliary solution, or "tracer" containing a known mass of the same element having the same isotopes but of different relative abundances or isotopic composition, and the induced change in the isotopic composition is measured by isotope mass spectrometry. This paper examines the optimisation of the estimated unknown amount of element in the sample solution to the known amount of element in the tracer solution. The aim is to minimise the relative uncertainty in determining the unknown amount of element.
