PYC-100A

PYC-100A

PMI’s Automated Gas and Helium Pycnometer 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 expands into a chamber containing the sample. Thus, the true volume obtained by pycnometry includes any pore volume accessible to the gas. Helium is the preferred gas, because it exhibits ideal gas behaviour.  However, almost any non‑corrosive gas, including air, can be used. The true density is obtained by dividing the weight of the sample by the true volume.
