[Data] Sugar particle size distribution (particle diameter distribution) and particle shape

[Data] Sugar particle size distribution (particle diameter distribution) and particle shape

Solving the challenges of sorting. We propose a new measurement method to obtain highly reproducible and reliable results, along with examples of sugar measurement.

This document introduces the particle size distribution (particle diameter distribution) and particle shape of sugar. The standard method for measuring the particle size distribution of sugar is sieving in accordance with the ICUMSA Method GS2/9-37, and equivalent results have been obtained in round robin tests conducted across multiple laboratories. However, in practice, each laboratory follows slightly different procedures from the ICUMSA Method guidelines, resulting in significantly different particle size distributions measured by different labs, which is a concern.

Scattering of light

Scattering of light

Diffraction, refraction, reflection

The fundamental theories of light related to our particle size distribution measuring instrument can be broadly categorized into "scattering," "diffraction," "interference," "refraction and reflection," and "absorption." The particle size distribution measuring devices handled by Nikkiso apply the phenomenon of light scattering to measure the particle size distribution based on the relationship between the intensity of scattered light and the size of the particles. The characteristics of each device will be explained later in the principles section, but here we will first explain the general phenomenon of "scattering." When we talk about light scattering, it often refers to everything other than the light that travels in a straight line when light is directed at a certain substance. In other words, it is the result of a combination of the three phenomena: "diffraction," "refraction," and "reflection." *For more details, please refer to the related links or feel free to contact us.*

Fresnel diffraction

Fresnel diffraction

Interference of secondary spherical waves

There are two teachers, Fresnel and Fraunhofer, who explained the phenomenon of diffraction. Fresnel explained this diffraction by considering the mutual interference of secondary spherical waves based on Huygens' principle, which is why it is also called the Huygens-Fresnel principle. "Each point on the wavefront at a given time acts as a source of secondary spherical waves, and the amplitude of the secondary waves decreases as the angle of inclination between the direction of the primary wave and the secondary wave increases, reaching a maximum when both waves are directed in the same direction and a minimum when they are directed in opposite directions. These phenomena arise from the mutual interference of the secondary spherical waves." *For more details, please refer to the related links or feel free to contact us.*

The relationship between the slit width and the diffraction light intensity pattern.

The relationship between the slit width and the diffraction light intensity pattern.

Light has wave-like properties.

I believe it is unnecessary to explain again that light has wave properties and that various optical phenomena change depending on its wavelength. Now, to organize the changes in the wavelength of light and the slit diameter that will be discussed, we will introduce parameters. λ: wavelength of light, D: slit diameter, which, as can be understood from the dimensions of the numerator and denominator, becomes a dimensionless number. As α becomes smaller, the diffraction intensity pattern of Fraunhofer diffraction mentioned earlier takes the shape shown on the right side of the figure, while as α becomes larger, it takes the shape on the left side. Now, considering λ as constant, the shapes produced will change depending on whether D is large or small. Here, I will expand a little on the equations to induce the reader's drowsiness and disguise the thin content. *For more details, please refer to the related links or feel free to contact us.*

Equation representing the intensity distribution of the diffraction pattern.

Equation representing the intensity distribution of the diffraction pattern.

Slit width of the opening = diameter of spherical particles

Until now, we have discussed diffraction in the context of illuminating an aperture, but for us, the manufacturers of laser diffraction particle size distribution measurement devices, it is fortunate that the same phenomenon can be observed when light is directed at the particles instead of the aperture hole. Furthermore, Mie theory is based on a single sphere, but it can also be applied to multiple spheres when the material and diameter are all equal, and they are distributed irregularly with a spacing that is sufficiently large compared to the wavelength. Conveniently for measurement device manufacturers, the amount of scattered light increases proportionally with the number of spheres. *For more details, please refer to the related links or feel free to contact us.*

Refraction and reflection

Refraction and reflection

Snell's Law

Have you ever had the experience of trying to spear a fish from above the water, only to miss? This happens because the position of the fish as seen from above the water is different from its actual position. In other words, this occurs because the light coming from underwater changes direction somewhere. This is called refraction. This issue of reflection is actually an important problem for instruments that use light scattering for measurement. If the angle of the scattered light entering the surface of the cell or the lens is not carefully designed, accurate measurements cannot be made. *For more details, please refer to the related links or feel free to contact us.*

Absorption

Absorption

Extinction and Adsorption

In this article, to distinguish between broad and narrow meanings, we will refer to the former as extinction and the latter as adsorption. For particle size analyzers, extinction is the more significant concept. First, let’s briefly explain absorption as a physical phenomenon. The presence of matter affects the propagation of light in various ways. This includes scattering, reflection, refraction, and the absorption we are discussing here. So why does this absorption occur? You know that light is a type of electromagnetic wave. This means that there is an oscillator with a certain frequency. *For more details, please refer to the related links or feel free to contact us.*

What is the difference between number distribution and mass (volume) distribution in particle size measurement?

What is the difference between number distribution and mass (volume) distribution in particle size measurement?

Even with the same particle size distribution, the way it is represented can greatly affect the shape of the distribution, so caution is required!

The number distribution is an image when measuring the size of particles with a microscope. In other words, it is a method of representing the number and size of particles as a distribution. In contrast, the mass (volume) distribution is an image when measuring the size of particles with a sieve. This means it is a method of representing the size of particles as a distribution of mass. Additionally, when measuring the particles by size (volume) instead of mass, it is referred to as volume distribution. Even with the same particle size distribution, the representation method (number distribution and volume distribution) can lead to significantly different shapes of the distribution, so caution is required. *For more details, please refer to the related links or feel free to contact us.*
