AB The identification and quantification of amorphous components and nanocrystalline phaseswith very small crystal sizes, smaller than ~3 nm, within samples containing crystalline phases isvery challenging. However, this is important as there are several types of systems that contain thesematrices: building materials, glass-ceramics, some alloys, etc. The total scattering synchrotron pairdistribution function (PDF) can be used to characterize the local atomic order of the nanocrystallinecomponents and to carry out quantitative analyses in complex mixtures. Although the resolution inmomentum transfer space has been widely discussed, the resolution in the interatomic distance spacehas not been discussed to the best of our knowledge. Here, we report synchrotron PDF data collected atthree beamlines in different experimental configurations and X-ray detectors. We not only discuss theeffect of the resolution in Q-space, Qmax ins of the recorded data and Qmax of the processed data, but wealso discuss the resolution in the interatomic distance (real) space. A thorough study of single-phasecrystalline nickel used as standard was carried out. Then, selected cement-related samples includinganhydrous tricalcium and dicalcium silicates, and pastes derived from the hydration of tricalciumsilicate and ye’elimite with bassanite were analyzed.
