METHODS The CID MS/MS spectra of adduct ions such as [M+H] + and [M+Na] + were measured by FAB, as well as some related characteristic ions. In addition, the high resolution data of characteristic ions were determined.

• 方法 利用FAB技术测定该类型 3种化合物的 [M +H]+和 [M +Na]+等不同加合离子 ,以及由其产生的特征碎片离子的CID MS/MS谱 ,并对有关特征离子进行了高分辨测定。
