Portable X-Ray Fluorescence Analysis of Rock Art Pigments
Plains Anthropologist, 2005Portable x-ray fluorescence technology has proved to be a very useful tool for identifying the mineral constituents of rock art paintings. This paper describes its use to identify chromium, whose likely source was the mineral fuchsite, as the green coloring agent in Montana and Wyoming pictographs.

A portable X-ray fluorescence spectrometer for the analysis of art objects
2005A field-portable X-ray fluorescence (XRF) analyzer was developed and assembled at the Academy of Fine Arts in Vienna in order to enable in-situ examinations in the field of archaeometry. The system is based on energy dispersive XRF using a 50 W X-ray tube of Oxford, type XTF5011, a silicon drift detector (SDD) of Röntec, type XFlash 1000, and two ...

Portable X-ray fluorescence analysis of Armenian obsidian sources
ARAMAZD: Armenian Journal of Near Eastern Studies, 2018During recent years the most effective and practical method for volcanic glass, commonly called obsidian sourcing is portable X-ray fluorescence (pXRF). In spite of the reliability of this method and the growing demand in recent years, the Armenian obsidian sources have been analyzed by using the above-mentioned analytical method only in the few ...

A Field-Portable X-Ray Fluorescence Instrument: Design and Applications
AIP Conference Proceedings, 2007The field portable XRF (FPXRF) spectrometer is composed of a measuring head that holds the detector (Si‐PIN) and the excitation sources (Cd‐109 and Am‐241) and the spectrum acquisition system. The application of this system for the analysis of cultural heritage artifacts will be presented and discussed.

Identification Techniques II: X-ray techniques and X-ray fluorescence with portable systems
2013Energy-dispersive X-ray fluorescence (EDXRF) portable spectrometers are becoming very popular in many fields for the on-site analysis of elements. This is mainly because EDXRF is a nondestructive, multielemental technique that is extremely well suited for the analysis of any material.

Handheld Portable Energy-Dispersive X-Ray Fluorescence Spectrometry (pXRF)
2016Handheld portable energy-dispersive X-ray fluorescence (pXRF) spectrometry is used for non-destructive chemical characterization of archaeological ceramics. Portable XRF can provide adequate analytical sensitivity to discriminate geochemically distinct ceramic pastes, and to identify compositional clusters that correlate with data patterns acquired by ...

Principles and applications of man-portable X-ray fluorescence spectrometry
TrAC Trends in Analytical Chemistry, 1994Abstract X-Ray fluorescence (XRF) spectrometry is perhaps one of the most widely accepted instrumental methods of analysis. The technique has the capability of simultaneous, multi-elemental, non-destructive analysis in a wide dynamic concentration range from 100% down to mg/kg levels with excellent relative precision of 1%.

Portable X-ray fluorescence instruments for the analysis of lead in paints.
Public health reports (Washington, D.C. : 1974), 1976In a study in the laboratories of the Chicago Board of Health, the results from determination of lead in paint films by X-ray fluorescence were compared with results from determination by atomic absorption. Portable instruments of three suppliers were used for X-ray fluorescence measurements.
