Analysis by pycnometry
Our laboratory performs helium pycnometry analysis to measure the true density of solid materials (eg powders) and viscous materials.
What is helium pycnometry?
A pycnometer is a laboratory tool used to measure the density and bulk mass of matter. Gas pycnometry is considered one of the most reliable methods for obtaining the bulk mass of a product. The helium pycnometer is used to determine the volume of a powder or bulk material according to Mariotte’s law and to deduce the density. Since helium has a small atomic diameter, it is able to penetrate into very small pores, thus making it possible to measure the density of porous materials.
Density analysis by helium pycnometry in the laboratory
Our laboratory performs the analysis with a pycnometer in order to determine the true density of solid or viscous materials.
This analysis may concern powders from all industrial fields and all types of materials (metal powders, polymers, etc.). The equipment completes our equipment park on the characterization of powders (apparent density, tapped density).
