SPECTROSCOUT Analysing Precious Metals

Analysing Precious Metals

Precious metals require, and reward, careful analysis. But analysts face various difficulties. The scope of precious metals analysis extends from trace levels to 100%. Most of these metals are resistant to dissolution by all but the strongest acids. Some traditional analytical methods like fire assay are time-consuming and demand a high level of skill.

Three modern techniques offer widely used solutions. Energy-dispersive X-ray fluorescence (ED-XRF) and optical emission spectrometry (OES) can be used without specialist analytical training to rapidly and accurately analyse bullion, jewellery, and alloys. A variation of OES, inductively coupled plasma optical emission spectrometry (ICP-OES), is an ideal tool for the analysis of bulk materials such as ores, and for the determination of trace impurities.

SPECTROSCOUT represents the state of the art in these techniques. This paper describes their application to precious metals analysis.
