A gas pycnometer determines the volume of a material by measuring the pressure change of an inert gas within two calibrated volumes. Density is calculated from the measured volume along with the mass of the sample.
Prior to analyzing, the gas pycnometer purges the sample with an inert gas to clean atmospheric gases, such as water and carbon dioxide, from the material. However, porous materials often require external preparation in order to obtain a clean sample.
