Measure the size distribution.
Laser light interacts with dispersed particles in the sample cell. The detected scattering pattern supports calculation of a particle-size distribution using the selected analysis settings.

CHARACTERISE / SERVICE 06
Particle size & shape.
Particle characterisation combines laser diffraction and dynamic image analysis to investigate particle-size distributions and shape.
THE QUESTION
How is particle size distributed through the sample?
A single average cannot describe every feature of a distribution. Review the measured spread, percentiles and repeatability alongside the preparation method to understand the material tested.
Methods & applications
- Laser diffraction particle-size distributions
- Dynamic image analysis of particle morphology
- Cumulative and differential distribution outputs
- D10, D50 and D90 percentile summaries
- Repeat measurements and comparison of runs
- Wet and dry analysis, selected for the material
HOW IT WORKS
Size and shape.
One connected measurement.
Capture particle shape.
A stroboscopic light source and camera capture individual particles as they pass through the cell. Image analysis adds shape measurements and particle imagery alongside the size distribution.

Explore the shape.
Size plots show the supplied three-measurement average; shape statistics describe the supplied first imaging run.
Volume distribution
Volume fractions per exported size bin—not a probability density. Source bin widths are unequal.
Cumulative distribution
D10: 63.69 µm · D50: 198.72 µm · D90: 308.88 µm
Volume-based percentiles from the supplied summary.
Particle shape · B/L ratio
7,196 particles · count-weighted, not volume-weighted. Ten equal-width ratio bins; not a mineral classification.
DYNAMIC IMAGE ANALYSIS

A clearly scoped delivery.
CTS is your point of contact for planning the programme and bringing the results together. Where specialist laboratory or interpretation input is required, delivery responsibilities are identified in your proposal.
The scope distinguishes the measurement package and its included outputs from additional processing, interpretation and interactive reporting. Sample requirements and method limitations are confirmed before work begins.

Interpretation boundary
Results describe the prepared particles under the stated measurement conditions. Dispersion and aggregation can affect the result. These measurements are distinct from CoreDNA image-derived grain-size estimates and do not measure pore-throat size.
