Photoionization Mass Spectrometry Detection Technology and Its Applications

Date:2025-06-04View:

Abstract:

By developing new key technologies and methods, we have independently developed multiple internationally advanced mass spectrometry instruments, including high-performance photoelectron-photoion coincidence imaging mass spectrometers, highly sensitive vacuum ultraviolet (VUV) photoionization free jet mass spectrometers, and aerosol mass spectrometers. These instruments enable high-sensitivity online detection via VUV photoionization mass spectrometry, and have been applied to photoionization mass spectrometry experiments on molecules, free radicals, and clusters in atmospheric and combustion reaction processes. This work provides important data and detection methods for in-depth studies on atmospheric chemical reaction dynamics.
