HPLC-ICP-MS traces showing Mn speciation of solutions of Mn2+-JED (top trace) and Mn3+-JED (bottom trace) incubated for 24 h, 37 °C, in human blood plasma. Mn3+- and Mn2+-JED elute at 8.0 and 10.9 min. Inter-conversion between the Mn3+- and Mn2+- complexes is slow, not reaching equilibrium within 24h.
