Approaches. Specific Gravity and Density tests can be used to identify a material or to follow physical changes in a sample. Specific Gravity and Density tests can also be used to indicate the degree of uniformity or variability among different sampling units or specimens, or to indicate the average density of a large item. ASTM Standards D1475.
For larger microspheres such as close to 1mm in diameter the density needs to match at least to 0.001gcc in order for the particles to stay suspended for some time. Particles below 200micron might be able to tolerate density mismatch of 0.005gcc. Particles below 50micron can potentially handle a difference in density of 0.01gcc.
