  • A feasibility study of the use of electrostatic deposition and laser induced fluorescence in a graphite furnace for size-segregated analysis of lead and gold in ultrafine (0.02-0.2 µm) particles

Abstract

The feasibility of determining lead in size-segregated ultrafine aerosols by laser-induced fluorescence (LIF) after deposition of the iso-mobility aerosol in a graphite furnace has been studied. The size-segregated analysis of the lead content in a test aerosol in the range 0.018 - 0.104 µm was performed. Polydisperse lead concentrations in atmospheric ultrafine aerosols were measured to be between 2.38 and 35.8 ng m{-3}. The mass fraction of Pb in the atmospheric particulate was calculated to be 4.81E-3. Finally, size-segregated analysis times range from several min for the case of Pb in an urban aerosol to many days for Au in average background aerosols.
