SIZE ANALYSIS OF FINE-PARTICLE SUSPENSIONS BY SPECTRAL TURBIDIMETRY -POTENTIAL AND LIMITS

In this paper, the potential and limits of turbidimetry as a particle sizing method are discussed with respect to several aspects, theoretic al and experimental. A complete experimental set-up consisting of a sp ectrophotometer and different types of in situ sensors, a data acquisi tion system, and a calculation program are described. The possible use s of this method for on-line measurements are discussed, particularly in the field of crystallization and powder technology. Two examples of its application are briefly presented.
