Abstract

Using a laser-ionization single-particle aerosol mass spectrometer (LISPA-MS), mass spectra of ammonium and sodium salt particles were obtained. In the negative-ion mass spectra, HSO 4 -, and NO 2 - and NO 3 - were dominant ions for (NH 4) 2SO 4 and NH 4NO 3 particles, respectively, while ions with sodium were also dominant for Na 2SO 4 and NaNO 3 particles. The chemical compositions of such salt aerosol particles can be inferred from the distribution of ions in those negative-ion mass spectra obtained using the LISPA-MS.
