heliumpycnometer
A helium pycnometer is a scientific instrument used to determine the density of a material by measuring the volume of a known mass of the material. The principle behind its operation is based on Archimedes' principle of buoyancy, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
The helium pycnometer typically consists of a sample chamber, a helium gas supply, and a pressure measurement
Helium pycnometers are particularly useful for measuring the density of porous materials, as they can accurately
The helium pycnometer offers several advantages over other density measurement techniques. It is non-destructive, meaning it
