In earlier days for determination of purity of gold a time consuming and hazardous fire assay method was commonly used. Other instrumental techniques, like AAS or plasma spectrometry, are highly expensive and sample preparation takes also longer time. Moreover, all these methods are destructive and involve the use of strong acids, high temperature and the production of toxic fumes. Because personal safety and costs are important factors MetExpert-GOLD is the right choice for checking precious metals. The MetExpert-GOLD allows non-destructive determination of precious and non-precious metals in high-quality alloys within seconds with high accuracy.

• The MS Windows based unique software of MetExpert automatically controls all functions of the spectrometer. Many thousands of measurements, including spectra, can be saved to hard disk and printed-out later or moved to another PC for further processing.
• MetExpert devices calculate the quantities of each element using its fundamental spectral data. No external calibration standards needed.
• MetExpert-GOLD device allows operator to preset the list of metals to be analysed. This option gives a possibility to estimate the minor metals with increased precision.
• diameter of a X-ray beam on explored object - no more than 1 mm (allows to conduct the detailed analysis of composite pieces of jeweler articles, elements of setting-up etc.)
• demountable measurement head with an opportunity of reference it on 1,5 m. from a spectrometer, (allows to yield the analysis of large-sized articles, such as the salaries of icons, ingots etc.)
• software product adapted under problems of testing supervision
• gadget for "strong" positioning of the data unit implements an opportunity of the "dot" analysis of composite surfaces

• MetExpert devices have 2 independed levels of protection from X-ray irradiation, which exclude any danger for operator.
