Table 1 summarizes four particle analysis techniques based on the main factors that should guide method selection. The solvent should not dissolve the particles or interact with them so that their shape or size changes. If the sample has to be dispersed, the solvent needs to be chosen carefully. Some analyses are performed on powdered materials and others on liquid dispersions. Some techniques can detect tiny nanoparticles, while others only work with larger particle sizes. Some methods assume that the analyzed particles are ideally spherical, making others better suited for non-spherical particles.Īpproximate particle size. The choice of the most appropriate PSD analysis technique depends on several factors, including the following: Which factors influence method selection? To make method selection easier, some of the most common particle size analysis techniques and the situations in which they are applicable are outlined below. Several analytical methods exist for determining particle size distributions, and it’s not always straightforward to select the most appropriate one. Different powders and dispersions are utilized widely in the production of food, paints, cosmetics, pharmaceuticals, electronics, biorefinery products, and semiconductors, making PSD analysis an essential step in the quality control, research, and development procedures of these industries. Particle size distribution (PSD) of solids or dispersed particles can be crucial for certain applications to ensure the functionality and safety of a product.
