本文报道了利用飞行时间质谱技术检测分子在XeCl准分子激光作用下产生的离子产物的结果,与四极质谱技术相比,飞行时间质谱检测手段充分体现了快速、微量的特色,这将使得飞行时间质谱检测技术得到广泛的实际应用。 当与脉冲激光相互作用时,分子通过选择性激光多光子电离及离解过程生成母体离子和
In this paper, we report the results of the time-of-flight mass spectrometry for the detection of ion products produced by XeCl excimer laser. Compared with quadrupole mass spectrometry, time-of-flight mass spectrometry detection method fully reflects the rapid and trace features that will make the flight Time MS detection technology has been widely used. When interacting with a pulsed laser, the molecule generates precursor ions by selective laser multiphoton ionization and dissociation
