Energy Dispersive X-ray Fluorescence Spectrometer
EDX-8000 SDD XRF Gold Analyzer
Overview
The assay lab that gives you completely non-destructive results in second
Jewelers, recyclers, and refiners of precious metals and alloys require elemental analytical capabilities that fit their challenging business conditions. Affordability is always key. Small operators have comparatively little cash for equipment. Larger concerns face constant pressure to keep costs low and profits high. However, affordability must still buy good performance. Percentages of gold, silver, and other precious metal alloys must be determined quickly and accurately, so that advantageous deals can be struck.
Now there is a proven, on-site solution providing laboratory-class results that are affordable, fast, and easy.
Features and Benefits
>Large sample chamber with the best performance Silicon Drift Detector
>Outstanding sensitivity leads to up to a factor 3 improved precision – the basis for high accuracy when analyzing minor to major element concentrations.
>World’s fastest XRF analyze–highest accuracy within the shortest measurement time, excellent precision
>High-count throughput detection system result in significantly (typically a factor 3) lower limits of detection for a wide range of elements.
>Easier, faster, more accurate than nitric acid test methods.
>Faster, more comprehensive analysis than fire assay, with comparable accuracy.
>Measure the content of all gold and precious metals without manually changing the calibration.
>Precisely determine the presence and concentration of other trace alloying elements and dangerous heavy elements, which could impact valuation and future refining needs.
