Kratky plot

A Kratky plot is a graphical tool used in small-angle scattering experiments to analyze how particles behave in a solution. It plots the intensity of scattered X-rays or neutrons against the scattering vector. This plot helps scientists understand the size, shape, and compactness of particles—like proteins or polymers—within the sample. When the plot levels off at higher angles, it indicates well-defined, compact particles; if it rises or falls differently, it suggests more flexible or dispersed structures. Overall, the Kratky plot provides insight into the structural characteristics of particles in a liquid environment.
