摘要

The element content as well as the particle size distribution of a new mussel candidate reference material was investigated. Instrumental Neutron Activation Analysis was applied for the determination of 15 elements in seven fractions of the material. Three vials of the candidate reference material and three coarser fractions were analyzed by Laser Diffraction Particle Analysis to determine the particle size distribution. Differences on element content were detected for fractions with different particle size distributions, indicating the importance of particle size control for biological reference materials.
