When light is scattered from a solution or a suspension, it undergoes random changes in intensity. This phenomenon helps us to determine the size of the particles that scatter the light. This is the ...

What is Particle Size Distribution Analysis? To determine the size and range of particles in a specific material, particle size distribution (PSD) analysis is used. Several techniques are used to ...

Dynamic light scattering techniques are used to determine particle size distributions of protein therapeutic formulations. In DLS-based measurement, scattering intensity changes are associated across ...

An expert on diffraction systems offers insight on particle size specifications and analysis. Specifications define the critical to quality factors to which a pharmaceutical product must conform to be ...

The author examines the process of method development, with reference to ISO 13320:2009 and relevant monographs from the United States and European pharmacopoeias. Particle size is a critical quality ...

Particles are contained in several types of materials. They are found in granules and powders like pharmaceutical ingredients, cement, and pigments. Particles are present in slurries, emulsions, and ...
