The use of portable XRF systems for preliminary compositional surveys on large bronze objects a critical review after s ome years' experience

摘要

The criteria by which X-ray flrourescence (XRF) is used to investigate large bronzes will problably undergo a substantial revision due to the miniaturization of the components and the consequent increased portability of the spectrometers. SOme years ago the authors started using a portable spectrometer for non-destructive compositional surveys in which the possibility of absolute quantitative determinations was not even considered; the spectroneter was simply used to detect-not to measure-compositional differences among different parts of the object.
