Laser Diffraction for Particle Size Analysis
Laser diffraction is the most widely used technique for particle size analysis. The methods have developed considerably over the years as had the capability to analyze over broad size range in a variety of dispersion media. Manufacturers and end users of powdered materials depend upon these accurate, reproducible, high resolution light scattering measurements to ensure full characterization of the particle size distribution of their sample.
NSL offers this particle size characterization analysis with the recent launch of our laser diffraction methods using the Malvern Mastersizer 3000. Laser diffraction is a well-established industry standard technique, defined by ISO 13320.
Our solution offers the following benefits:
- A detection range of 100 nanometers to 3.5 millimeters for dry media, and 10 nanometers to 2.1 millimeters for liquid dispersions
- Accuracy within 1 percent
- Repeatability better than 0.5 percent
- Reproducibility better than 1 percent
A large variety of material types can be analyzed including:
- Powdered metals and oxides
- Suspensions of polymers
Applications include measuring the particle size distribution of pigments and materials used in the following:
- Optical coatings
- Electronic devices
- Solar cells
- Wear resistant coatings
- Medical devices
ISO 13320 for laser diffraction was first published in 1999. It has nearly replaced the sizing of particles by sieve analysis and is relied upon by numerous industries that produce or use powders and particles, such as pigments and powder metals, to ensure the quality of their products.
