Efficiency of Portable X-ray Fluorescence for Distinguishing Lead Slag
Applied Spectroscopy, 2023 In the Minier Valley (France, Aveyron), an archaeological site excavation has led to the discovery of 25 kg of lead (Pb) slag, found in a secondary position. On a macroscopic level, these slags can be classified into two distinct categories, vitreous black and porous gray.

Portable x-ray fluorescence spectrometer for coating thickness measurement [PDF]
Review of Scientific Instruments, 2007 A handheld x-ray spectrometer has been realized and tested. The purpose of the device is to measure the thickness of coated samples in the range of 1–1500nm in an industrial environment. Accuracy of ∼3% has been achieved in this range with a measurement time of 1min.
