用MassLynx 4.1软件提取液相色谱质谱联用部分重叠色谱峰的质谱图

目的两个化合物A和X采用液相色谱质谱联用法实现部分分离,并形成部分重叠峰。尝试在不改变分离条件的情况下获得化合物X的"较纯的"质谱图。方法运用MassLynx 4.1软件的"谱图合并(Combine Spectra process)"功能,扣除化合物A的信号。结果与预期相符,所获得的质谱图明晰,提示X可能是A的脱氢类似物,后经验证,与A脱氢类似物纯品的质谱图一致。结论 Masslynx 4.1软件的"谱图合并"功能可以帮助分析者更容易地获得清晰的质谱信息,并有可能节省传统方法中优化色谱条件所花费的时间,是液相色谱质谱联用分析的有力工具。
