摘　　要：自行研制了一台配置了激光离子源的射频离子阱质谱仪 ,并测试了该仪器的一些主要功能 .测试结果显示 :该仪器不仅能记录激光产生的正负离子的质谱 ,而且能实现离子质量选择存储和囚禁离子的共振射出 .测试结果与理论模拟的结果基本一致 .Performance of the radio- frequency ion trap mass spectrometer has been tested.The mass spectrometer is a home- made instrument interfaced with a laser desorption ion source.The experiment demonstrated that the instrument can not only record the mass spectrum of the cations and anions produced by the pulsed- laser beam but also exhibit the special functions,such as ion selective storage and resonant ejection of the ions in the trap. The observation of the experiment is consistent with the simulation result.
