Particle analysis is a research area that involves the study of the size, shape, composition, and behavior of particles, such as atoms, molecules, and nanoparticles. This field typically uses various techniques, such as microscopy, spectroscopy, and chromatography, to characterize and analyze particles in order to understand their properties and interactions. Particle analysis is commonly used in a wide range of scientific disciplines, including materials science, chemistry, biology, and environmental science, to study and manipulate particles for various applications.
