使用电喷雾质谱检测了在不同溶剂条件下的绵白糖溶液。实验结果表明不同绵白糖溶液在电喷雾质谱检测中表现出不同的特点，如在碱性条件下有利于负离子的形成，在甲醇溶液中能观察到单糖的质谱峰等。尽管绵白糖的成分比较简单，但是在质谱中表现十分复杂。采用串联质谱技术分析了这些溶液中化合物的碎裂规律，通过其碎裂方式确定了其质谱峰的归属。所建立的电喷雾质谱方法，灵敏度高，定性能力强，操作简便快速，可以作为糖产品的重要检测方法之一。

In this test , several soft white sugar solutions were detested by electrospray ionization mass spectrometry (ESI-MS) . The results show that every solution presents some characteristics in ESI-MS , for example , basicity favors anion forming ;and the peaks of monosaccharides can be observed in methanol solution of soft white sugar .Although the constituent of soft white sugar is simple ,its mass spectra are rather complex .In this test ,the compounds in the soft white sugar solutions were analyzed by tandem mass spectrometry ,by which the peaks were assigned .ESI-MS can be used to analyse soft white sugar solution with high sensitivity , strong qualitative ability , simply and easy handle . Thus it can be important method for sugar analysis .
