Elemental Analyses Of Archaeological Bone Using Pxrf, Icp-Ms, And A Newly Developed Calibration To Assess Andean Paleodiets, Christine L. Bergmann

USF Tampa Graduate Theses and Dissertations

As a result of the quick rise of pXRF technology in archaeology, there are concerns regarding the reliability and validity of data output acquired from pXRF. In this study, I test the hypothesis that portable X-ray fluorescence (pXRF) spectrometry can provide reliable and valid results, using newly developed calibration curves, for the analysis of archaeological animal and human skeletal materials in prehistoric Peru to address hypotheses about ancient diet and trade. While pXRF systems may come with calibration software, the few if any standards and reference materials provided with the instrument rarely correspond to the vast array of archaeological materials …
