Notes
- Pycnometer is the preferred spelling in modern American English usage. Pyknometer is to be found in older texts, and is used interchangeably with pycnometer in British English. Pyknometer is preferred in European English.
- The density calculated from the volume measured by a gas pycnometer is often referred to as skeletal density, true density or helium density and sometimes as particle density for non-porous solids.
- One of the most extreme examples of the gas displacement principle for volume measurement is described in U.S. Patent 5,231,873 (Lindberg, 1993) wherein a chamber large enough to hold a flatbed truck full of timber is described for the purpose of measuring the volume of the load.
