Sets out a procedure for indirect determination of high purity gold after determination of impurities by Inductively Coupled Plasma-Atomic Emission Spectrometry ICP-AES. The method is suitable for gold and gold alloys containing more than 99.95 percent gold.

Scope

This Standard sets out an instrumental procedure for the indirect determination of high purity gold after determination of impurities by Inductively Coupled Plasma–Atomic Emission Spectrometry (ICP–AES). The method is suitable for gold and gold alloys containing more than 99.95% gold.
Consideration should be given to the origin, manufacture and final use of the product in identifying the list elements to be tested. The following list of elements is not necessarily complete: Ag, Al, As, Be, Bi, Ca, Cr, Cu, Fe, Ir, Mg, Mn, Ni, Pb, Pd, Pt, Rh, Se, Si, Sn, Te, Ti, Zn.
It is recommended that a qualitative scan be carried out on unknown material to assist in identifying any elements additional to the list.
NOTE: This is an intricate procedure and should be performed only by an analyst familiar with the chemistry of the technique and the operational procedures of the instrument used.
