This paper describes the recent development of an instrument designed to allow real-time measurement of the size and chemical composition of individual aerosol particles. We focused on the principle and features of aerodynamic sizing, then combine it with laser desorption ionization time-of-flight mass spectrometry, and the real-time measurement of wood smoke particles was performed.-
