Helium Pycnometry - Lab(E13)

---

Helium Pycnometry A pycnometer is used to accurately determine the bulk volume as part of density determination. The system is filled with helium. The volume of each section of the system is known. The pressure is measured before and after a section at atmospheric pressure is added. The ideal gas law is used to determine the volume of a specimen.The mass is measured separately and combining the volume and mass information, we get the density, density = mass/volume.
