在任何质谱计中,特别在飞行时间质谱计中,离子源的工作是很关键的。因为组成直线飞行时间质谱计的三个主要组成部分(即离子源、分析部分和接收检测部分中的分析部分)实际上只是一段消极的无场自由漂移管道,所以仪器的性能主要决定于离子源的工作,并受离子接收器与有关电子设备的限制。飞行时间质谱计中离子的形成和引出尤其重要。因为离子 In any mass spectrometer, especially in the time of flight mass spectrometer, the work of the ion source is critical. Because the three main components that make up a linear time-of-flight mass spectrometer (ie, the ion source, the analysis section, and the analysis section in the reception detection section) are really just a passive, field-free drift tube, the performance of the instrument depends primarily on the ion source Work, subject to the limitations of the ion receiver and related electronic equipment. The formation and extraction of ions in the time of flight mass spectrometer is especially important. Because of ion
