Determination of particle size distribution. Single particle light interaction methods - Light scattering aerosol spectrometer1 Scope This part of ISO 21501 specifies characteristics of a light scattering aerosol spectrometer (LSAS) which is used for measuring the size, number concentration and number size distribution of particles suspended in a gas. The light scattering technique described in this part of ISO 21501 is based upon single particle measurements. The size range of particles measured by this method is between approximately 0,06 m to 45 m in diameter. Instruments
