An Improved Density Gradient System for Forensic Science Soil Studies
The density of a homogenous material is one of the more useful of its properties. Being dependent on the nature and composition of the material, it can be used as both a point of identification of the substance and a comparison of its composition with similar substances; being constant, affected only by temperature, it is reproducible. Techniques and equipment exist to easily and precisely measure the density of most liquids and solids. The basic techniques and applications of density measurements in the field of forensic science are covered by Kirk [1,2].
