A method was devised to determine the isomeric composition of an ionic mixture using collisionally activated decomposition mass spectrometry. Compared with the more rigorous approach based on collision cross‐sections reported previously, the main advantage of the proposed method is its experimental simplicity. Both the internal consistency and the accuracy of the method were tested for mixtures of isobaric ions, i.e. ions with the same nominal mass‐to‐charge ratios.
