Particle Size Result Interpretation: Number vs. Volume Distributions. Interpreting results of a particle size measurement requires an understanding of which technique was used and the basis of the calculations. Each technique generates a different result since each measures different physical properties of the sample.

All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it. (One exception might be extremely narrow distributions,

In order to simplify the interpretation of particle size distribution data, a range of statistical parameters can be calculated and reported. The choice of the most appropriate statistical parameter for any given sample will depend upon how that data will be used and what it will be compared with. For example, if you wanted to report the most common particle size in your sample you could,

Performing a particle size analysis is the best way to answer the question: What size are those particles? Once the analysis is complete the user has a variety of approaches for reporting the result. Some people prefer a single number answer—what is the average size? More experienced particle scientists cringe when they hear this question, knowing that a single number cannot describe the,

Particle Size Analysis. Across most sectors, the particle size of products and materials is a critical parameter in their manufacture. Changing the particle size distribution of a material has a massive impact on its characteristics and it’s behaviour either during its manufacture, within the final product or on its effects within the environment. For example, the particle size distribution,

The procedure of determining the proportion of mineral particles in each of these classes is called particle size analysis or mechanical analysis of the soil. In soil analysis, the proportion of gravel and larger particles is determined by first grinding the soil to disaggregate it and then passing it through a 2 mm sieve. What remains in the sieve is weighed and it's proportion calculated as,

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.

A relatively basic but effective particle size analysis method is by sieve analysis. Particle Technology own a full range of ASTM standardised test sieves and automated sieve shakers. The sieves are selected based on sizes of interest ranging nominally from 20 microns to ~3mm. They are placed with the smallest sieve at the bottom and the sample is added to the top sieve. As the sieve shaker,
