Simultaneous determination of iron, copper and zinc concentrations in skin phantoms using XRF spectrometry

X‐ray fluorescence analysis was used to determine the concentrations of iron, copper and zinc in skin phantoms. The system used consisted of a high‐output tungsten target x‐ray tube and a germanium secondary target, the fluorescence from which was used to excite the elements in the sample. Calibration models were constructed in order to allow quantitative predictions of metal concentrations, with spectral analysis performed using the Marquardt …
