gas pycnometer

A gas pycnometer can be used to measure the volume of a powder sample.

A gas pycnometer is also sometimes referred to as a helium pycnometer.

There is also a gas-based manifestation of a pycnometer known as a gas pycnometer.

Gas expansion pycnometer is also known as constant volume gas pycnometer.

The working equation of a gas pycnometer wherein the sample chamber is pressurized first is as follows:

A common laboratory device for measuring fluid density is a pycnometer; a related device for measuring the absolute density of a solid is a gas pycnometer.

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.

The volume measured in a gas pycnometer is that amount of three-dimensional space which is inaccessible to the gas used, i.e. that volume within the sample chamber from which the gas is excluded.

A gas pycnometer is a laboratory device used for measuring the density - or more accurately the volume - of solids, be they regularly shaped, porous or non-porous, monolithic, powdered, granular or in some way comminuted, employing some method of gas displacement and the volume:pressure relationship known as Boyle's Law.
