Jewellery - Determination of palladium in palladium jewellery alloys - ICP-OES method using yttrium as internal standard element

<p>ISO 11495:2014 describes a method for the determination of palladium in palladium jewellery alloys, preferably within the range of fineness specified in ISO 9202, by means of inductively coupled plasma optical emission spectrometry (ICP-OES).</p> <p>The preferred palladium content of the alloys lies between 500 ? (parts per thousand) and 950 ? palladium.</p> <p>NOTE This method can be used to analyse other contents of palladium.</p> <p>This method is intended to be used as the recommended method for the determination of fineness in alloys covered by ISO 9202.</p>
