将基体辅助激光解吸电离飞行时间质谱这种新兴的质谱方法用于植物中寡糖的分析.比较了不同的样品制备方法和检测方式对分析结果的影响,给出各寡糖样品的分子量分布、单体和端基基团的分子量.
The new method of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MS-MS / MS) was applied to the analysis of oligosaccharides in plants.The influence of different sample preparation methods and detection methods on the analytical results was compared, the molecular weight distributions of each oligosaccharide sample were given, The molecular weight of monomers and end groups.
