Combined method for determining low gold and silver contents with assay melting and subsequent spectral analysis of the solution.
Determination of gold at low concentrations-from 0.05 g/t.
Combination of assay melting and subsequent spectral analysis of the solution.
The method is used when standard assay analysis is not sufficient to accurately determine small concentrations.
Determination of precious metals after dissolution of the gold-silver crown.
The assay method with atomic absorption termination is used to increase the sensitivity and accuracy of the analysis when determining low gold and silver contents.
The method combines assay melting with subsequent spectral determination of precious metals. After assay melting, the resulting gold-silver kinglet is dissolved in aqua regia, and then the resulting solution is analyzed by an instrumental method.
As a final step, atomic absorption spectroscopy (AAS) or inductively coupled plasma atomic emission spectroscopy (ICP-AES) can be used. Modern devices allow you to determine small amounts of a substance in solutions.
The assay-atomic absorption method makes it possible to determine the gold content from 0.05 g/t. As a result, the method is widely used in modern analytical laboratories when working with materials with low concentrations of precious metals.
Data on gold and silver content in materials with low concentrations of precious metals.
Ability to determine gold from 0.05 g / t after assay preparation and spectral analysis.
