Comparative Density Measurements for Solid Specimens Weighing a Few Milligrams
A density comparison technique previously described has been used to compare the densities of tungsten wires weighing about 1.3 mg to within a few percent error. For larger, less dense specimens the expected random error of a few parts in 10(4) was confirmed by comparing the known densities of Si an...
