Performance validation of ScatterX78 against NIST reference materials
SAXS measurements were performed on a set of nanoparticle size reference materials from NIST. The experimental data acquired with ScatterX78 were analyzed with the EasySAXS software to determine the nanoparticle size distributions. All results were found to be precise and accurate, and in good agreement with the values given by NIST. Additional tests on multi-modal particle size distributions demonstrated the power of the indirect Fourier transformation approach for data analysis.
