摘要
Cefquinome was studied by ESI and EI mass spectrometry,and its structure was proved from mass spectrometry. The results indicated that ESI positive ion of cefquinome included[M+H]+529,395.5,323.6,166.6.the main fragmentations of EI MS involved m/z 528,395,239,225,33,132,105,91,77,44,and so on.The structure segment accorded with its cracking.
