True density, of powders

Density can be defined as ratio of the mass of an object to its volume therefore, the density of a solid is a reflection of the arrangement of molecules in a solid. In pharmaceutical development terms, knowledge of the true density of powders has been used for the determination of... 

A helium pycnometer is used to measure the true density of powder materials. The automated pycnometers run tests and report data from consecutive runs that are within a user-specified tolerance. This instrument can be used to perform particle density measurements on various composite and polymeric materials.
