Six Errors in Particle Analysis and How to Avoid Them

Fig. 4: Particle size distributions of a sample of coffee powder determined with sieve analysis (black *), laser diffraction (orange *) and dynamic image analysis. Image analysis provides three results based on particle width (red), particle length (blue) or circle equivalent diameter (green). The definition 'width' fits well with sieve analysis, laser diffraction tends to correspond to circle equivalent diameter. arrow back arrow forward Image Zoom
