Abstract
A method for determining the presence of crystalline silica particles in a sample comprising a plurality of particles. The method comprises: receiving first data generated based upon light scattered by at least one particle of said plurality of particles; receiving second data generated based upon intensity and polarization change of the light transmitted through at least one particle of said plurality of particles; and determining the presence of crystalline silica particles in the sample based upon the first data and second data.
