title: Determination of magnesium at trace levels by isotope dilution.
abstract: A mass spectrometric method for the isotopic analysis of magnesium and its determination at low concentrations in the presence of an excess of other elements is described. The lowest level at which magnesium was determined was 1 ppm with a precision and error +/- 1%.
