Analyzing Chocolate with the Morphologi® G3 and Wet Cell Accessory
29 Apr 2014Particle size measurement is already established as a useful tool for testing the final product quality of chocolate. In this application note it is shown that the Malvern Morphologi® G3 Automated Particle Characterization System equipped with the wet cell accessory can be used characterize chocolate in terms of both size and shape of the particles. Additionally, the intensity of the grey scale images recorded during the analysis provides further information.

Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
