Comparison of Sieve analyses, laser diffraction, image analyses and FBRM for the determination of particle size distributions part 6 The results obtained from LD instrument as the conversion has been done from a number-based PSD to volume-based PSD for the IA measurements. The IA and LD gave very similar results for spherical particles, as these […]

Comparison of Sieve analyses, laser diffraction, image analyses and FBRM for the determination of particle size distributions part 4 Focused Beam Reflectance Measurement (FBRM). A Lasentec (FBRM) was used to measure the chord length distribution (CLD) of samples using a Lasentec D600L FBRM probe. In all the experiments, the measurements were carried out in suspensions […]

Comparison of Sieve analyses, laser diffraction, image analyses and FBRM for the determination of particle size distributions part 2 LD estimates volume-based PSD by measuring the forward light-scattering (diffraction) of light from the laser. It is one of the most widely used techniques because of its range of applicability, ease of implementation, broad dynamic range, […]

Comparison of Sieve analyses, laser diffraction, image analyses and FBRM for the determination of particle size distributions part 1 Abstract Particle size distributions (PSDs) measured by different techniques, including Sieve Analyses (SA), Image Analysis (IA), Laser Diffraction (LD) and Focused-Beam Reflectance Measurement (FBRM), were investigated. The two compounds selected for the study were spherical glass […]
