Particle Size Analyzer

Light scattering is one of the most widely used techniques for measuring particle size distribution. In practice, the technique is fast and flexible, offering precise measurements.

The Coulter measures the size distribution of particles that are suspended in a liquid or in dry powder form using the principles of light scattering. This scattered light pattern is generally called a scattering pattern or scattering function. More specifically, a scattering pattern is the intensity of light as a function of the scattering angle. Each scattering pattern of a particle is characteristic of its size.

This particle size analyzer provides reliable and reproducible results for researchers, quality control laboratories, process and product control departments or anyone who needs to measure particle size distributions.
