Abstract
An Assessment of Analytical Techniques For The Size Analysis of Fine-Grained Sediments

ABSTRACT
An evaluation of techniques for the size analysis of fine-grained sediments revealed that the Malvern Laser Sizer (E3600), Electrozone Particle Counter (Model 112), Micromeritics SediGraph (5000E), and hydrophotometer work well for the analysis of sorted silt. Differences in results may be attributed to the particle property being measured by each instrument. The Malvern Laser Sizer and Electrozone Particle Counter are sizing techniques; the hydrophotometer and SediGraph determine sedimentation diameter through particle settling. There was less agreement among these instruments for unsorted natural sediments containing greater than 15 percent clay by weight. Clay content of less than or equal to 8 percent does not appear to decrease the resolution of silt-sized particles.
