We utilize the pin tube sampling method while your metal is still in its molten state, ensuring a 100% homogeneous sample. We then deploy fire assay with ICP and atomic absorption technology, which can measure in parts per billion, ensuring that we are paying for every bit of your precious metal.
Classic Fire Assay
Other Dental Refiners
Many of the leading dental refiners sample the metal by drilling into it after it has been melted and cooled. They then collect the shavings and analyze them using simple X-Ray technology. This process lacks precision and can cost dental practices hundreds or even thousands of dollars annually.
