  • White Paper: Comparison of Methods

    Different measuring techniques provide different results – but what is the truth? The most common techniques to determine the particle size distribution are dynamic image analysis (DIA), static laser light scatter-ing (SLS, also called laser diffraction) and sieve analysis. This white paper presents the advantages and drawbacks of each technique, their comparability among each other as well as detailed application examples.
