MEASUREMENT OF GOLD IN JEWELRY GOLD-ALLOYS

The determination of gold is one of the post prominent analytical issues of precious-metals chemistry. Due to the chemical nature of the element gold, gravimetric methods could be developed - weighing the gold itself - which are so far unrivalled in terms of their quality. In the light of the so-called cupellation as a criterion, the use of spectrometry generally means a real venture. The performance of ICP solution spectrometry in an analytical frontier area is described by the example of gold.
