Determination of particle size distribution. Single particle light interaction methods - Light extinction liquid-borne particle counter Ingestion-build-264231 Note: BS EN 13652 method1 Scope This document describes a calibration and verification method for a light extinction liquid borne particle counter (LELPC), which is used to measure the size and particle number concentration of particles suspended in liquid. The light extinction method described in this document is based on single particle measurements. The typical size range of particles measured by this method is between 1 m and 100 m in particle size. The method is
