Laser Diffraction Particle Size Analysis is a non-invasive and exceptionally accurate method employed to assess the particle size distribution within a sample. This technique capitalizes on light scattering principles, where particles traversing a laser beam scatter light at angles inversely correlated to their sizes. Through the analysis of the scattered light pattern, the instrument can precisely ascertain the size distribution of particles in the sample, offering crucial insights into their physical characteristics.
The underlying principles of Laser Diffraction Particle Size Analysis are rooted in the Mie theory of light scattering. When a particle passes through a laser beam, the light interacts with the particle, causing it to scatter at specific angles. The intensity and angular distribution of the scattered light are directly related to the size of the particle. Larger particles scatter light at smaller angles, while smaller particles scatter light at wider angles.
By applying the Mie theory, the instrument can accurately calculate the particle size distribution based on the observed scattering patterns. This mathematical model takes into account factors such as the wavelength of the laser, the refractive index of the particles, and the refractive index of the surrounding medium, ensuring a precise and reliable analysis.
At CD BioSciences, we pride ourselves on offering a comprehensive Laser Diffraction Particle Size Analysis service to our clients. Our team of highly skilled experts is dedicated to providing reliable and accurate results, ensuring that our clients can make informed decisions about their environment-friendly materials.
Our Laser Diffraction Particle Size Analysis service utilizes state-of-the-art equipment and industry-leading methodologies to ensure the highest quality data. We offer both wet and dry analysis methods, depending on the nature of the sample and the specific requirements of the project.
Wet Analysis
For liquid dispersions or suspensions, the sample is introduced into the instrument's measurement cell, where it is circulated to ensure a homogeneous distribution. The laser beam passes through the sample, and the scattered light is detected and analyzed.
Dry Analysis
For dry powder samples, the material is dispersed in an air stream and passed through the laser beam. The scattered light is then measured and used to determine the particle size distribution.
We cater to a variety of sample types, including:
Powders
Dry samples that are analyzed in an air stream.
Liquids
Wet samples suspended in a liquid medium.
Emulsions
Samples that require stabilization in a liquid for analysis.
Suspensions
Solid particles dispersed in a liquid medium.
