Standard Guide for Size and Shape of Solid Particles, Liquid Droplets, and Gas Bubbles, Dynamically Conveyed, Using a Dynamic Imaging Analyzer

Importancia y uso:

4.1 This guide is intended to inform those who have need for particle analysis data of their product or process, how imaging technology, in the form of a DIA, can be employed to provide the required information for a wide range of processes and material types. It expands on dynamic imaging information provided in Guide E2651 which is a broad view of particle analysis methods.

4.2 This guide can be used to assess the suitability of the technology to particular applications as well as any limitations that may be encountered. It is also intended to help the user make an informed decision on how to best use the technology to make the measurement(s) most important in providing data that best describes the process or product.

4.3 Determining particle shape of materials such as proppants, catalysts, additive manufacturing powders, and many more materials, is critical to their performance. Imaging technology can provide a consistent assessment of shape factors based on objective criteria and a statistically significant number of particles analyzed. Human visual methods generally compare a small number of particles to a standard leaving room for subjective interpretation.

4.4 Determining particle count, size and shape are important in assessing contamination of fluids such as fuels, lubricating oils, water, injectables, and other liquids where particle contamination can affect their performance. Particle shape can point to the type and source of these particles which can help analysts improve process control.

4.5 Shape information is also advantageous in categorizing particles detected so as to not skew particle analysis results. For instance, if a flowing mixture of solid particles in liquid also contains gas bubbles or water droplets, it is important to be able to identify the bubbles and droplets and not count them as solid particles.
