Development of a Mobile Resonance Enhanced Multiphoton Ionization Time of Flight Mass Spectrometry (REMPI MS) Analyzer for Real-Time Ultra-Trace Gas Phase Monitoring

本项目将开发一种移动的气体分析仪，用于检测超痕量（ppt）水平的NO、NO2和芳烃。该仪器基于共振增强多光子电离飞行时间质谱（REMPI/MS），具有高度选择性的实时检测，在环境压力下对空气直接采样，时间分辨率小于1秒。固态激光技术和光纤将被使用，使仪器坚固耐用和移动的。

In this project, a mobile gas analyzer for the detection of NO, NO2, and aromatic hydrocarbons at the ultra trace (ppt) level will be developed. The instrument is based on resonance enhanced multiphoton ionization time of flight mass spectrometry (REMPI/MS) and will feature highly selective real-time detection, direct sampling of air at ambient pressure, and a temporal resolution shorter than one second. Solid state laser technology and fiber optics will be used, making the instrument rugged and mobile.
