Figure 5: Identification of metal–DMA and metal–NA complexes in japonica rice shoots by ESI-MS/MS.

Metal–DMA (a) and metal–NA (b) complexes in shoot extracts of japonica rice were identified in positive ESI mode with hydrophilic HILIC column separation by UPLC-ESI-Q-TOF-MS. The spectra of the released free metals were obtained in MS/MS with fragmentation energy 50 eV.
