09419 IUPAC Gold Book - relative isotopic sensitivity factor 10.1351/goldbook.09419 09419 current 1 In dynamic secondary-ion mass spectrometry, coefficient for an element by which the measured intensity for an isotope of that element, divided by the measured intensity for a matrix ion, is multiplied to yield the atomic concentration of that isotope of the element present in the sample. Matrix terms are strong, and the matrix, bombarding species, incident-ion energy, and angle of incidence, as well as the spectrometer operating conditions, all affect relative elemental sensitivity factors significantly. dynamic secondary-ion mass spectrometry https://goldbook.iupac.org//terms/view/09183 PAC, 2020, 92, 1781.
