Species-selective isotope dilution mass spectrometry and substoichiometric isotope dilution mass spectrometry were studied to develop the determination methods of different chemical species such as antimony(III, V) and copper(I, II) as well as boron(III) as boric acid. The proposed methods were applied to the analysis of several certified reference materials and the reliability, accuracy, and applicability were evaluated
