Precision Particle Size Testing for Every Industry
Understand your material’s performance with accurate PSD analysis via laser diffraction
Particle Size Distribution (PSD) Testing
Particle Size Distribution (PSD) testing is a method used to determine the range and proportion of particle sizes present in a material sample. It identifies the percentage of particles within specific size intervals—also called size classes or fractions. For example, in a sample of grinding balls, these size classes might be 5 mm, 10 mm, 15 mm, and 40 mm. Understanding the distribution of these sizes helps assess the material’s performance and suitability for its intended use.
Definition
PSD refers to how particles of different sizes are distributed within a material. It shows what sizes are present and how much of each size exists in the total sample.
Importance
PSD testing is critical in many industries and research fields:
In soil science, it influences texture, water retention, and compaction.
In pharmaceuticals, it affects drug dissolution, stability, and bioavailability.
In environmental science, PSD helps analyze particulate matter (PM), which can be harmful to human health. Particle Number Size Distribution (PNSD) data is especially useful in identifying PM sources and forming control strategies.
Measurement Methods
Various techniques are used to measure PSD:
Sieving – for larger particles, using meshes of different sizes.
Laser diffraction – for fine particles, measuring how light scatters as it passes through the sample.
Scanning Electron Microscopy (SEM) – for detailed imaging of particle shapes and sizes.
Presentation of Results
PSD data is essential for:
Quality control – ensuring consistency in materials like powders or granules.
Process optimization – refining milling, blending, and mixing operations.
Material characterization – analysing properties of substances such as minerals, pharmaceuticals, and construction materials.
