文摘

In situ secondary ion mass spectrometry (SIMS) analysis requires the use of standards to unravel the instrumental mass fractionation (IMF) induced by the analytical procedures. Part of this IMF might be caused by the nature of the sample and the differences in composition and structure between the sample and the standards. This “matrix effect” has been tentatively corrected for by using standards with chemical compositions equivalent to the samples, or by the empirical use of chemical parameters. However, these corrections can only be applied to a narrow compositional range and fail to take proper account of the matrix effect when a wider chemical field is tested.
