There are two fundamentally different methods of analysis of the SAXS spectra:1. an approach independent on model of nanoparticles, and 2.direct modeling . The first proposed by Glatter consists of a Fourier transform of spectrum data to obtain an autocorrelation function for the particle average for ensemble, and of procedure of deconvolution of this function to obtain the profile of the radial electron density of the nanoparticles. Direct modeling begins from an assumed geometrical model of the nanoparticles and then the calculation of the SAXS intensity of the nanoparticles dispersions in accordance with the model and optimization of parameters of nanoparticles model by minimization of the error functional are performed.
It is necessary to calculate the size of the spectrum, then the distribution. The calculation is designed for the device.
Thanks. But I am looking for some free software via which I can get the distribution just by inserting my data and needed parameter like geometry of particle.
