Guinier model

The Guinier model is a scientific way to analyze how tiny particles or structures in a sample scatter X-rays or neutrons. It helps determine the size and shape of these particles by examining how the scattered intensity changes at very small angles. In simple terms, the model provides a relationship that allows scientists to estimate the average size of the smallest components within a material, such as nanoparticles or biological molecules, giving insight into their structure without needing to see them directly.
