Influence of Gas Flow on Ion Transport in PTR-MS Drift Tubes Using an Electro-Hydrodynamic Coupled Model

Abstract Proton transfer reaction mass spectrometry (PTR-MS) is widely used for the real-time detection of volatile organic compounds (VOCs). Previous efforts to improve PTR-MS sensitivity have mainly focused on electric-field optimization, whereas the influence of macroscopic ga...
