ISO 11494:2014描述了通过电感耦合等离子体发射光谱法(ICP-OES)测定铂首饰合金中铂的方法,优选在ISO 9202规定的细度范围内。
该方法适用于可能含有银,铟,铱,镓,铜,钴,镍,锡和钌的铂金首饰合金。但是,这个清单并不详尽,总是要注意调查潜在的干扰效应
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.
