The Quantachrome Ultrapyc 1000 Gas Pycnometer measures the structural or apparent density of solid or particulate materials using gas displacement. In this method, helium gas is used to access the open porosity in the sample. The apparent density of the material is calculated by determining the volume of the sample by introducing a known quantity of gas into the chamber at two different pressures. The relationship P1V1=P2V2 is used to calculate the volume, and the density is determined by dividing this into the mass of the sample. For materials with closed porosity, this results in the apparent density. For materials without closed porosity, this results in the true density.
