Abstract
A novel method for the determination of the particle and cell-size distribution is adapted for the optimization of feedstock pre-treatment and measurement of the fluid phases of mono-cultivation and complex anaerobic digestion bioprocesses. The method relies on laserlight backreflection of particles, which are hit by a rotating focus beam. Due to the different patterns of backreflection at the edges cores of particles, sizes of them can be determined in situ.
