The Guinier region in small-angle X-ray scattering (SAXS) defines the radius of gyration, <i>R</i><sub>g</sub>, and the forward scattering intensity, <i>I</i>(0). In Guinier peak analysis (GPA), the plot of <i>qI</i>(<i>q</i>) <i>versus q</i><sup>2</sup> transforms the Guinier region into a characteristic peak for visual and automated inspection of data. Deviations of the peak position from the theoretical position in dimensionless GPA plots can suggest parameter errors, problematic low-resoluti ...[more]
