Assaying is the examination or measurement of a material to answer defined questions about composition or content. For precious metals, the relationship between the material, the sampling plan and the analytical technique is central to interpreting the result.
Explore sampling, precious-metal content, method suitability and assay interpretation.
The suitable approach depends on the material, the intended outcome and the details agreed by the parties.
Make a service enquiryDifferent specimen forms and questions call for different considerations. The following themes help frame the discussion.
An assay may focus on the proportion of a precious metal, relevant accompanying constituents or characteristics required for a particular decision. Different sample forms call for different preparation and evaluation considerations.
Industry methods can include fire assay, X-ray fluorescence and instrumental chemical analysis. These are examples rather than a list of instruments operated by ASL; the appropriate technique depends on material, required analytes, sensitivity and agreed scope.
A report needs to link each stated result to the particular specimen examined, its identity and measurement units. When results inform a larger lot, sampling representativeness and any technical limitations should also be considered.
A few useful details can make your first enquiry much more focused.
