Jewellery - Determination of platinum in platinum jewellery alloys - ICP-OES method using yttrium as internal standard element (ISO 11494:2014)

Scope

ISO 11494:2014 describes a method for the determination of platinum in platinum jewellery alloys, preferably within the range of fineness specified in ISO 9202, by means of inductively coupled plasma optical emission spectrometry (ICP-OES).
This method applies to platinum jewellery alloys that might contain silver, indium, iridium, gallium, copper, cobalt, nickel, tin, and ruthenium. However, this list is not exhaustive and care is always to be taken to investigate potential interference effects.
