Some polycyclic aromatic hydrocarbons (PAHs) are considered to be cancer‐causing chemicals, and ion mobility spectrometry (IMS) is used for on‐site detection of such hazardous chemicals. In IMS, the ionization behavior of analytes is affected by the types of reactant ions (RIs). In the present work, the influence of different types of RIs on the ionization behaviors of PAHs in an ion mobility spectrometer equipped with a corona discharge ionization source was investigated using various RIs.

电晕放电-离子迁移谱法中不同类型反应物离子对多环芳烃电离行为的影响。

一些多环芳烃（PAH）被认为是致癌化学物质，并且离子迁移谱（IMS）用于现场检测此类危险化学物质。在IMS中，分析物的电离行为受反应离子（RI）的类型影响。在目前的工作中，使用各种RI研究了在配备电晕放电电离源的离子迁移谱仪中，不同类型的RI对PAHs电离行为的影响。
