Detection of New Diffusion Treatments
GemTOF collects almost all elemental information in the periodic table routinely. When performing a daily measurement, system control computer, displays a first glance of the composition of the gemstone when it is being ablated. Already, abnormal signal intensity can be readily spotted at an earliest stage. It is therefore adapted to detect new and undisclosed chemical treatments in the form of unknown diffusion treatments or coatings. And thus it will help to avoid an unprepared situation such as when beryllium diffusion treated corundum hit the market (and gemmological laboratories) at the turn of the century.
