WebFor all tasks in polymer research, development and production quality control, X-ray Fluorescence (XRF) analysis can identify and quantify the concentrations of additives (pigments, fillers, flame retardants, stabilizers) such as antimony, barium, bromine, calcium, chromium (in accordance with RoHS/WEEE regulations), copper, phosphorus ... Web(2013). Small-angle X-ray scattering (SAXS) is normally employed to probe the polymer structures, such as the radius of gyration (R g) and thickness of the lamellar crystal for which the dimensions are in the nanometer range. However, it is important to note that the key to the X-ray scattering techniques is the quality of the X-ray source. psych spread sheet reddit 2022
