There are lots of technologies accessible to figure out particle size distribution of materials. Of all the technologies readily available, laser diffraction is becoming one of the more widely used and desired techniques. This post will have a look at a number of the much more broadly accepted tactics found in different industries nowadays. Particles are a few-dimensional things. As a way to supply a full outline of a particle, a few factors are needed – length, breadth and elevation. As a result, it can be difficult to describe a particle using a single quantity that equates to the size. Consequently, most sizing techniques believe that the material getting calculated is spherical as a sphere is the only shape which can be described by an individual quantity, its diameter, hence simplifying the way particle size distributions are displayed.

Laser Diffraction

Laser diffraction is the one of the more widely used particle sizing strategies and is among the most common approach in lots of industries for characterization and control. The particle distribution analysis will depend on the truth that particles transferring via a laser ray will spread gentle with an perspective that is immediately linked to their size. When particle size reduces, the witnessed scattering position improves logarithmically. Scattering high intensity can also be at the mercy of particle size, decreasing with particle volume. What this means is that sizeable particles scatter gentle at filter perspectives with high intensity whilst small particles spread at broader angles with very low strength. Laser diffraction includes a vast vibrant range, from .2 to 2000 microns which is very fast and reputable. Additionally it is very accommodating as it can be put on dry powders, aerosols and emulsions. In addition, laser diffraction fails to demand calibration but can be easily verified. Vibrant gentle scattering is surely an correct, trustworthy and repeatable technique.


This really is a classic technique commonly used in the color and ceramics industries. The main advantage of this technique is that it determines particle size being a purpose of deciding viscosity. Even so, as the denseness from the material is necessary, this technique is not any beneficial to emulsions where material does not negotiate or for thick material that settles too rapidly. Additionally it is according to spherical particles, so will give large mistakes for particles huge factor rate.

Image Analysis

This technology generates information by recording straight images of every particle, delivering customers with all the ultimate awareness and resolution. Image analysis systems are capable of high-resolution sizing starting from .5µm – 1000µm. delicate differences in particle size and shape might be effectively characterized applying this method.

Acoustic Spectroscopy

Rather than employing light, this technique uses sonography for collecting information about the particles that are dispersed in water. This can be achieved due to the fact dispersed particles absorb and scatter sound surf in the same manner to light. Acoustic spectroscopy can be used to measure particle size distribution for just about any particle inside a fluid system and will measure at very high particle concentrations.
