Portable X-ray fluorescence analysis of Armenian obsidian sources

ARAMAZD: Armenian Journal of Near Eastern Studies, 2018
During 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, 2007
The 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.

Principles and applications of man-portable X-ray fluorescence spectrometry

TrAC Trends in Analytical Chemistry, 1994
Abstract 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%.

Handheld Portable Energy-Dispersive X-Ray Fluorescence Spectrometry (pXRF)

2016
Handheld 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 ...

Portable X-ray fluorescence instruments for the analysis of lead in paints.

Public health reports (Washington, D.C. : 1974), 1976
In 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.
