Guinier approximation

The Guinier approximation is a mathematical method used in small-angle scattering experiments to analyze how particles are distributed in size within a sample. It simplifies the relationship between the scattered light (or X-rays) and the size of the particles, especially at very small angles. By applying this approximation, scientists can determine the average size and how these particles are spread out without needing complex calculations. Essentially, it’s a tool that helps us understand the structure of tiny particles in a material by interpreting scattering data at low angles.
