Density Analysis / Density measurement in laboratory
Density analysis is a key step in the characterization of raw materials, formulations and finished products.
Would you like to perform a density analysis on your materials?
The density of a material corresponds to the ratio between its mass and its volume.
It reflects the compactness of the material and provides information about its internal structure, porosity, composition and homogeneity.
This physical property, studied in materials characterization, varies depending on the nature of the matrix (liquid, bulk solid, powder).
Our solutions: comprehensive density analysis techniques
FILAB laboratory offers a range of complementary techniques to determine the true, bulk or functional density of a wide variety of matrices: liquids, organic or metallic powders, polymers, resins, bulk parts, composite materials, etc.
Our density analysis techniques
- Tapped density (powders)
- Bulk density (Archimedes’ principle)
- True density (helium pycnometer)
- Density measurement using capillary densimeter
Application case – Density analysis in polymers
In the polymer industry, density measurement is used to verify formulation homogeneity or detect deviations related to material changes, filler content variations or process modifications.
A non-compliant density may indicate mixing issues, residual moisture or composition variations.
➡️ This analysis helps secure quality control and adjust processing parameters.
Application case – Density analysis in metallurgy
In the metallurgical sector, density analysis is used to evaluate the compaction of metal powders intended for sintering or to check the integrity of bulk parts.
A density that is too low may indicate excessive porosity likely to affect mechanical properties, while an abnormally high density may point to material contamination or a process defect.
➡️ The objective is to identify the root cause of the deviation and optimize the manufacturing process with the support of a specialized laboratory such as FILAB.
Laboratory density measurement
Using a laboratory for density measurement allows you to:
- verify material compliance with specifications or internal standards
- monitor formulation consistency or detect production drift
- assess material porosity or compaction
- understand powder behavior during transport, dosing or shaping steps
- compare different supply sources or qualify a new supplier
- optimize a process, formulation or processing parameters
