  • The use of isotope dilution mass spectrometry (IDMS) to make measurements of amount of substance that are traceable to the International System of Units (SI) depends on an analysis of possible sources of uncertainty. A comprehensive application is presented of the law of propagation of uncertainty to the two-way IDMS method, which allows sensitivity coefficients to be calculated and optimum regimes identified for carrying out IDMS measurements. This has allowed the effect of deviations from… CONTINUE READING
