摘要
This paper took Mo isotopes as an example to introduce the principle, illustrate the calculation method of high-precision measurement isotope composition with double spike, and demonstrate the analytical method with multi-collector inductively coupled plasma-mass spectrometer (MC-ICP-MS). On the premise of that the instrument fractionation and the nature fractionation follow an exponential law, a system of nonlinear equations was converted to a system of linear equations using the
