Figure 3: Proposed mass fragmentation pathways and product ions of metal–DMA and metal–NA complexes.

From: Identification of metal species by ESI-MS/MS through release of free metals from the corresponding metal-ligand complexes

Figure 3

Mass product ions (lower panels) of metal–DMA (a) and metal–NA complexes (b) were obtained in positive ESI mode with Obritrap-MS under different fragmentation energies, HCD: 40–90%. The proposed fragmentations and fragmentation pathways ((1)–(4)) are shown with dotted lines and arrows, respectively, accordingly to the m/z of product ions shown. “Free metals” on arrow indicates the fragmentations where the release of free metals was observed primarily. Asterisks denote the highest abundant fragments. “Me” in the structures represents the “Metal”.
