Every detail you need to know about particle size analysis

Knowing more about why is particle size so paramount for researchers or about the methods used to complete this process is absolutely essential for a better understanding of the topic. When working in such field, being able to understand and interpret the details related to particle size distribution calculus, central values, widths of distribution, image analysis and so on can help you progress faster. Contacting a team of specialists to deal with particle size characterization for you might be the best option you have, but you also need to be able to check each information you receive.

Concepts as distribution basis and points, values, reproducibility, distribution errors, analysis techniques and so on should be explained. Starting with setting up particle size specifications, you’ll have to make sure you understand what a distribution base is. Well, the primary results one will obtain when dealing with particle size analysis would consist of certain values that include numbers, volumes, different weights, surface areas, intensities etc. Usually, a rule of setting up these specifications is general and is used in order to format the final result of the analysis.

The same goes with distribution points, where specialists do not use a single number to represent the distribution of a particle size because this technique is not the one recommended. A unique data point cannot offer enough stable information to go further with the analysis, even though many specialists tend to use an average particle size number to specify the result obtained. Yet, there are some cases when one single distribution point is recommended, and it is called the mid-point of a particle size distribution or the median. Other size parameters are often used to describe other characteristics that don’t usually matter in the long run. Depending on your situation you should ask the company that is dealing with your particle size characterization job whether to include or not include certain values.

Image analysis is another concept that one needs to be familiarized with. Using the image analysis technique means that one can avoid having to analyze additional values in the process. Image analysis allows finding out more about certain parameters, including aspect ratio and particle morphology. Choosing the correct technique when wanting to obtain specific particle size values is essential because otherwise the process will take longer, and the values obtained will be less important for the final results.

Another interesting concept that you might want to know about would be the static image analysis. When talking about an automated stage of the particle size characterization process, using a microscope or a digital camera to collect information about each particle. In order to be able to read all the information you are being given or the information you obtain after undergoing each process, you’ll have to learn more about the existent dynamic ranges of each particle characterization systems. Plus, you should know what instruments are being used for this characterization because this can highly influence the final results.
