Density specifies how much of a substance occupies a defined volume at a stated temperature and pressure. The density of a substance can be used to define the substance and it performance characteristics.
Controlling the density of finished goods is often desirable for performance as well as economic considerations. For this reason, many manufacturers strive to develop materials that are partially porous yet still fulfill their function while others seek an end product of maximum density.
Accurate density measurements are an important part of characterizing the physical properties of ceramic and foam raw materials. Density analysis can also be used to determine the performance of parts fabricated with Additive Manufacturing. In pharmaceutical manufacturing, density is a key data point utilized in roller compaction operations, and can be used as an indicator of tablet strength and dissolution rate.
Density influences the overall quality of manufactured products and density analyzers provide data that guides the manufacturing process. For this reason, Micromeritics gas pycnometers (AccuPyc and GeoPyc) are used worldwide to determine the density of raw materials and finished products.
