A single-particle aerodynamic relaxation time (SPART) analyzer was developed to measure the aerodynamic size distribution of aerosol particulates in the range of 0.1 to 10.0 m In diameter. The analyzer sizes and counts individual suspended particles and droplets from sampled aerosols, determines their aerodynamic diameter, and generates the size distribution in real time. The measurement is independent of the electrical and optical properties of the particles. The size range and resolution of the SPART analyzer depend on the acoustic frequency. Operating at 27 kHz, the instrument's effective sampling rate was calibrated in the range of 0.3 to 6.0 /micrometre using test aerosols containing monodisperse polystyrene latex spheres (PLS) and olive oil droplets. The instrument counts and sizes aerosol particulates at a maximum rate of 200 particles/ sec. The sensing volume of the instrument is approximately 10~5 cc; this allows the size distribution of an aerosol containing a relatively high particulate concentration to be measured without an appreciable coincidence loss. |
