QSAXSPreprocessing 1.1 — a cross-platform application for preprocessing data of small-angle X-ray scattering from a polydisperse nanoparticle system

A cross-platform application, QSAXSPreprocessing, with a graphical user interface is presented — a software implementation of the procedure for correcting the indicatrix of small-angle X-ray scattering, accounting for contributions from large particle agglomerates and atomic-scale inhomogeneities. The application uses the Numpy, Scipy, and Matplotlib libraries and is a software package consisting of modules written in Python3, combined into a unified interface based on the PyQt5 library. The current version of the application has been tested on Windows 10/11 and Ubuntu 28.1. QSAXSPreprocessing 1.1 has been successfully used for the analysis of small-angle X-ray scattering from nanoparticle powders.
