Laser diffraction measurements capture information about particle size distribution by measuring scattering intensity as a function of the scattering angle, wavelength and polarization of light based on applicable scattering models. This is an absolute method that …

Laser Diffraction Analysis. Laser diffraction is the most commonly used technology for measuring particle size distributions in paint systems. With a typical analysis time of less than one minute, this method is widely used for many process control applications.

The LS 13 320 XR boosts laser diffraction particle size analysis to the next level, with its enhanced PIDS technology and extended measurement range providing higher resolution and more accurate, reproducible results.

The LS 13 320 XR particle size analyzer uses advanced laser diffraction and PIDS technology for the sizing of non-spherical, sub-micron particles. Initially, particle sizing by laser diffraction was limited to the use of the Fraunhofer diffraction theory.

Sizing Pigments Using Laser Diffraction Analysis A variety of particle sizing technologies have been employed to measure the particle size distributions of pigment systems. But, laser diffraction has increasingly become the most commonly employed technique in the determination of particle size distri-butions. The acceptance of the technique ...

Considering only the visible part of the electromagnetic spectrum, the interaction of light and matter produces four inherently related scattering phenomena. We differentiate these phenomena by the words diffraction, refraction, reflection, and absorption.

Smaller particles pose a real challenge for laser diffraction technology. When illuminated by a laser beam, large particles scatter light at low angles with easily detectable maxima and minima in the scattering pattern.

Beckman Coulter Life Sciences presents a video on particle size characterization by laser diffraction analysis in geoscience and soil science.

Beckman Coulter's LS 13 320 XR is an easy-to-use laser diffraction analyzer that yields fast, reliable particle size analysis data for dry and aqueous and non-aqueous samples.

State-of-the-art laser-diffraction technology for analyzing particles with the highest resolution and accuracy, and without risk of missing the largest or smallest particles in a sample.
