True Density – He

Helium Pycnometer, True Density Testing,  is used to determine the true volume and true density of powders and bulk solids using high-precision volume measurements and density calculations. The true volume of a solid is calculated from the measured drop in pressure when a known amount of gas is allowed to expand into a chamber containing sample. Thus, the true volume obtained by pycnometer includes any pore volume accessible to the gas. Helium is the preferred gas, because it exhibits ideal gas behavior.
