Resumen

This document describes an analytical method for the determination of silver in jewellery alloys with a nominal content of up to 990 ‰ (per mil), including alloys according to DIN EN ISO 9202 using inductively coupled plasma emission spectrometry. Preferentially the silver content of the alloys lies between 50 ‰ (parts per thousand) and 990 ‰ silver. NOTE Lower contents of silver can be analyzed with this method.
