Traditional fire assay analysis is labor-intensive, expensive and environmentally harmful. Thus, the Thermo Scientific ARL iSpark 8860 Fire Assay Analyzer offers a simple, clean alternative to the traditional cupellation and analysis stages by using spark optical emission spectrometry (OES) in order to determine precious metals concentrations directly in lead buttons. Simultaneous quantitative determination of the content of all precious metals in fire assay lead buttons can be achieved in less than a minute. The ARL iSpark 8860 Fire Assay Analyzer is a top of range spark optical emission spectrometer specially tuned for the analysis of lead buttons.
