"The fractionation of a sediment sample into a number of size classes is frequently needed to study the effect of sediment size on a number of sediment-contaminant interaction processes. In this paper, a laser particle size analyzer was used to test the effectiveness of the filtration technique that is often used for fractionation. The results indicate that the filteration technique is not adequate even for a fully dispersed inorganic sediment. The fractionation of environmental samples that are likely to flocculate need innovative approaches"--Management Perspective.
