EID tandem mass spectrometry of singly-charged electrosprayed ions of octaethylporphyrin (OEP) and its iron(III) complex results in ionisation to give doubly-charged precursor and fragment ions. Singly-charged fragments are also observed. EID fragmentation differs significantly to that observed in electron ionisation mass spectrometry.
八乙基卟啉（OEP）及其铁（III）配合物的单电荷电喷雾离子的 EID 串联质谱导致双电荷前体离子和碎片离子的电离。也观察到单电荷碎片。EID 碎裂与电子离子化质谱中观察到的碎裂有显著差异。
