A world of possible applications

Construction industry: Determination of the density/porosity of materials here e.g. concrete core samples. A whole pile of individual concrete cores, some with broken edges

What are gas pycnometers used for?

And in which sectors are they particularly useful?

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

It is used to determine the density (also skeletal density, pure 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, general solids and component densities. It is also used to test the composition of 2-component (heterogeneously composed) composites or mixtures (e.g. testing the metal content) and to determine the internal porosity (void volume fraction of closed pores) with a 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 the density/porosity of materials
  • For example: Wood, concrete, lightweight building materials such as plasterboard, lightweight concrete, pumice, asphalt, floor coverings, foam glass for insulation and aerated concrete.

Chemicals | Pharmaceuticals | Cosmetics

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

Paint industry

  • Color pigments

Geology | Mineralogy

  • Core samples: Measurement of the porosity of drill cores
  • Evaluation 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
  • Carbon fiber reinforced plastic (CFRP), glass fiber reinforced plastic (GFRP), wood fiber composites
  • For example: in plastics technology for aircraft and spacecraft construction, in vehicle construction (automotive industry), in the manufacture of sports equipment

Mineral Resources & Mining

  • Roller compacting
  • Bulk material compaction

Recycling

  • Copper scrap
  • Composite materials
  • Particle technology in chemistry, process engineering, processing technology, separation technology and sorting technology

Sintered materials

  • Powder metallurgy: Measurement of sintering & casting densities to check for cavities
  • Sintered materials in general
  • Powder metallurgy, cold isostatic pressing (CIP), hot isostatic pressing (HIP)
  • Ceramic materials (technical ceramics, also sanitary ceramics)

And much more
