  • Development of a portable reference Aerosol Generator (PRAG) for calibration of particle mass concentration measurements
    Particuology, 2018
    Co-Authors: François Gaie-levrel, Soleiman Bourrous, Tatiana Macé

    Abstract:

    The tapered element oscillating microbalance with filter dynamics measurement system (TEOM-FDMS) is an instrument commonly employed by the French air quality monitoring network. This instrument is currently calibrated with calibration weights traceable to SI but having value and mass differences between each of them that are not representative of real atmospheric particle mass measurements. Moreover, these calibration weights do not allow detection of any technical problems associated with either the TEOM-FDMS sampling system upstream of the mass measurement or the intrinsic TEOM-FDMS filtration system. Therefore, a calibration method was developed using a portable reference Aerosol Generator (PRAG) that produces known and stable particle mass concentrations over time. Here, we present the characterization of the PRAG system in terms of a reference range of particle masses between 30 ± 10 and 3456 ± 83 μg at three sampling times. Its coupling with the TEOM-FDMS and a global comparison between the defined reference range of particle masses and the measured masses obtained with each TEOM-FDMS implicated in this study are also presented. © 2017 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences

  • A monodisperse sulfuric acid Aerosol Generator
    Atmospheric Environment, 2003
    Co-Authors: S.m. Wall

    Abstract:

    Abstract A simple sulfuric acid Aerosol Generator which provides a reproducible Aerosol of narrow size distribution has been developed. The method is based on the injection of heated SO3 vapor in N2 into a stream of humidified air. Particle diameter is adjustable from approximately 0.3 to 1.5μm with a relative standard deviation of between 0.12 and 0.20. The Generator is also capable of producing particles of 1.5 μm under special conditions. The sulfuric acid Aerosol size distribution was obtained from optical particle counter data and verified using electron microscopy. The sulfuric acid concentration range of the Generator is 0.3–3 mg m−3 depending upon the particle size produced.
