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.

在该项目中，将开发一种用于检测超痕量 (ppt) 水平的 NO、NO2 和芳香烃的移动气体分析仪。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、环境压力下的空气直接采样以及小于一秒的时间分辨率。将使用固态激光技术和光纤，使该仪器坚固耐用且可移动。
