Figure 7.

Relative isotopic abundances of the M+1 and M+2 peak for all elemental compositions that would fit a measured mass of 774.94831 Da (Cangrelor), determined at 1 ppm mass accuracy (values exceeding 100% are removed in graphics). Most formulas can be discarded if isotope ratios are measured with an accuracy of ± 5% and used as search constraint (red box).
