C_(60)和C_(60)/C_(70)的激光脱附飞行时间质谱分析

Investigation of laser desorption TOF mass spectra of C_(60) and C_(60)/C_(70)

采用激光脱附并直接测量离子的方法对实验室提取的C_(60)/C_(70)以及进一步分离得到的纯C_(60)进行了飞行时间质谱分析,并讨论了质谱分析过程中实验条件对结果的影响.

The TOF mass spectra were measured for the laboratory extracted C60/ C70 and chromatographically purified C60 by directly detecting the laser desorbed ions. The dependence of mass spectra on the experimental conditions was discussed.
