Abstract

See full text

The invention concerns a method and system for determining particle size information of particles contained in a sample, the method comprising illuminating the particles with at least three light sources placed on different locations, detecting light reflected from the particles using a detector capable of spatial resolution, and processing the output of the detector so as to determine the particle size information. According to the invention, the particles are illuminated simultaneously with the at least three light sources each operating at a different wavelength channel, and the wavelength channels are simultaneously detected at the detector. The invention reduces the need for sample preparation, among other benefits.
