The gas pycnometer allows for the determination of the skeletal density of nanoporous materials using helium pycnometry. To determine the skeletal density, a sample with known mass is put in the sample chamber. The sample chamber is pressurzied with the inert gas helium. After stabilization of the pressure, a valve to a reference chamber of known volume is opened. After equilibration of the pressure, the volume of the sample can be derived from the pressure.
