Measurement techniques used with HORIBA analyzers.

• Static Light Scattering
• Laser Diffraction
• Low Angle Light Scattering (LALS)
• Fraunhofer Diffraction
• Mie Scattering

Measurement of particle size by analyzing the angular dependence of the light scattered from the particles. This is applicable over a wide size range from 0.01-3000 microns.

How does this technique work?

Used by HORIBA models: LA-950V2, LA-930, LA-300.

• Dynamic Light Scattering
• Photon Correlation Spectroscopy (PCS)

Measurement of particle size by analyzing the interaction of the incident light with the Brownian Motion of the particles. This motion causes a Doppler Shift in the light relative to the vibration frequency and size of the particles. Applicable to smaller particles over a range from 1nm to 6 microns.

How does this technique work?

Used by HORIBA model: LB-550.

• Digital Image Processing
• Image Analysis

Measurement of particle size and shape by analysis of images captured by digital cameras. Each particle is analyzed for individual characteristics and the total is summed for the whole analysis. Applicable over sized from 30 microns to 30mm.

How does this technique work?

Used by HORIBA model: CAMSIZER.

• Electroacoustic Zeta Potential

Measurement of the surface change (zeta potential) of particles in suspension by analyzing the colloid vibration current in response to particle motion due to acoustic waves.  

How does this technique work?

Used by HORIBA model: DT-1201.

• Acoustic Attenuation Spectroscopy

Measurement of particle size in concentrated suspensions by analyzing the attenuation of acoustic waves at different frequencies and detector geometries. Applicable over a range from 5nm to 100 microns.

How does this technique work?

Used by HORIBA model: DT-1201.
