| 摘 要： | 2-氨基吡啶硝化产物2-氨基-3-硝基吡啶和2-氨基-5-硝基吡啶的一级质谱图接近,单纯通过一级质谱图较难区分这两种异构体.利用离子阱质谱的串联质谱技术对2-氨基-3-硝基吡啶和2-氨基-5-硝基吡啶在离子阱内以He作碰撞气进行碰撞诱导裂解,所得的二级质谱图表明,两者之间存在明显的差别,可用于2-氨基吡啶硝化产物2-氨基-3-硝基吡啶和2-氨基-5-硝基吡啶的鉴别.

| Abstract: | A method has been developed using MS/MS to qualitatively differentiate 2-Amino-3-nitropyridine and 2-Amino-5-nitropyridine.2-Amino-3-nitropyridine and 2-Amino-5-nitropyridine were analyzed by GC-MS and GC-MS/MS,and the mass spectra were discussed.It was shown that MS analysis does not offer a solution due to the spectral similarity of these isomers.But MS/MS analysis can clearly differentiate these isomer due to the spectral difference of these isomers. |
