252-Californium plasma desorption mass spectrometry was applied to the study of five different classes of phospholipids namely phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine and phosphatidylinositol. Positive and negative ion spectra were compared to spectra obtained using other ionization techniques. Plasma desorption mass spectra provide useful information on the molecular weight of compounds from all classes, particularly in the case of phosphatidylserine--a class that has failed to show satisfactory quasimolecular ions with either Fast atom bombardment, FAB or Field desorption, FD. The observed fragmentation is also indicative of the structure of the studied compounds.
252-锎等离子体解吸质谱法被应用于研究五种不同类型的磷脂，即磷脂酰胆碱、磷脂酰乙醇胺、磷脂酰甘油、磷脂酰丝氨酸和磷脂酰肌醇。将正离子和负离子光谱与使用其他电离技术获得的光谱进行了比较。等离子体解吸质谱为所有类型化合物的分子量提供了有用信息，特别是在磷脂酰丝氨酸的情况下——这一类化合物在用快原子轰击（FAB）或场解吸（FD）时未能显示出令人满意的准分子离子。观察到的碎片也表明了所研究化合物的结构。
