摘要
采用电喷雾电离质谱(ESI)和质谱(MS)-质谱(MS)技术分析了两种工业有机磷酸--氨基三亚甲基膦酸和羟基亚乙基二磷酸。用ESI-MS技术获得了有机磷酸产品及主要副产品的准分子离子峰,用ESI-MS-MS技术获得了其碎片信息,为检验产品及主要副产品的结构提供了证据。
Two industrial organophosphates - amino tri ( methylene phosphonic acid ) and hydroxyethylidenediphosphonic acid were analyzed by ESI-MS, MS -MS techniques. The quasi-molecular ion peaks of the above organo - phosphates and major by - products obtained with ESI - MS and the fragmental information by further ionization obtained with ESI-MS-MS, together provided reliable structure information of the samples.
