Construction industry: determination of density/porosity of materials - concrete core samples for example

What are gas pycnometers used for?

And in which industries are they particularly useful?

The BULKINSPECTOR is a cross-sectional instrument for a wide range of industries, but it is mainly used in the field of physico-chemical analysis (general research & automated laboratory analysis), monitoring and quality control (production, offline in the laboratory or online in plants).

It is used to determine the density (also skeletal density, true density) and mixed density or apparent density of solids.

Roughly summarized, it can be said that it is used for the analysis of pure substances, generally solids and component densities. In addition, it is used for compositional testing of 2-component (heterogeneously composed) composites or mixtures (e.g. testing of metal contents) and determination of internal porosity (void volume fraction of closed pores) with known solid density (e.g. foam).

Additive Manufacturing | Rapid Prototyping

Component characterization by determining the solid content in 3D printing

Building materials technology

Determination of density/porosity of materials
For example: Wood, concrete, lightweight materials like gypsum board, lightweight concrete, pumice, asphalt, flooring, foam glass for insulation, and aerated concrete.

Chemistry | Pharmaceuticals | Cosmetics

Determination of properties/characteristics: purity of products, chemical conversion by reaction, water content, thermal expansion coefficient, etc.
Chemistry: fertilizer industry
Pharmaceuticals: determination of tablet compaction and detection of pore inclusions
Pharma: Active pharmaceutical ingredients (API)
Cosmetics: detection of pore inclusions in lipsticks

Color industry

Color pigments

Geology | Mineralogy

Core samples: measurement of porosity of drill cores
Assessment of the proportion of liquid absorption / gas absorption of minerals

Composites | Plastics

Quality assurance of foamed plastics
Determination of the filler content of plastics/composites
