Advanced methods for in situ chemical and bio processes analysis based on the Laser back-reflectance measurement technology

Determination of the particle size distribution (PSD) is one of the most important tasks to monitor and control for most of chemical and bio-processes. In continuous movement of particles under effects of the carrying fluid, PSD determination is a technically challenging. This article summarizes some researches in which Laser back reflectance measurement method was used for in-situ and in real time PSD analysis. Two processes are selected to introduce including: crystallization of the amino acid L-arginine and biological processes.
