摘要: 设计了一种用于质子转移反应质谱的新型漂移管结构,称之为锥面漏斗漂移管,该漂移管由20 片传统的环形 电极和5 片新型锥面电极组成。首先通过离子轨迹仿真验证了该新型漂移管的离子聚焦效应,随后进一步开展对比实 验验证了该新型漂移管的性能。研究结果表明,相比于传统漂移管,新型锥面漏斗漂移管具有更软的电离效果和更高 的灵敏度( 4.0~6.3倍)。并且,与传统射频聚焦方法不同,新型锥面漏斗漂移管仅通过直流电场即可实现离子聚焦,无 需额外的射频电源,特别适用于需要小型化和低功耗的仪器,以提高检测灵敏度。

Abstract: A new drift tube structure for proton transfer reaction mass spectrometry, called conical funnel drift tube, is designed in this work, which is composed of 20 traditional ring electrodes and 5 new conical electrodes. Firstly, the ion focusing effect of the new drift tube is verified by ion trajectory simulation, and then further comparative experiments are conducted to validate the performance of the new drift tube. The results show that the new conical funnel drift tube has a softer ionization effect and higher sensitivity (4.0– 6.3 times) than the traditional drift tube. Moreover, different from the traditional RF focusing method, the new conical funnel drift tube can realize ion focusing only through DC electric field without the need of additional RF power supply, making it especially suitable for instruments requiring miniaturization and low power consumption to improve detection sensitivity.

Key words: conical funnel drift tube, direct current electric field, ion focusing, sensitivity
