- Abstract:
- The emergence of hand-held X-ray fluorescence devices (HH-XRF) has changed the cultural approach to the analysis of ancient materials. These instruments are characterised by highly miniaturised hardware and powerful software and much of the designer s efforts are devoted to encourage users to consider the device as a black box, with no need to go into the substance of its functioning. For those who prefer to go into the substance instead, this paper discusses some preliminary activities necessary to prepare it for the field. In particular, we discuss the optimisation of the primary filter and the calibration of two XRF devices i.e. a hand-held Bruker Tracer 5g and an in-house developed portable spectrometer, by considering two quantitative parameters: the limit of quantification and the relative uncertainty of quantification.
