| Abstract: | A method for using Malvern laser particle size analyzer in the determination of particle size distribution of chromium catalyst is discribed. The catalyst sample is evenly dispersed in distilled water and passes through laser beam at a certain flow rate. The diffraction light received by the detector is transformed into particle size distribution. The experiences of application are discussed. The method is accurate, easy to establish and very suitable to be used in production process. |
