[ 1 ] - Promotion of the Cupellation Method for Accurate Determination of Gold Alloy’s Karat Containing Platinum-Group Metals
The main standard method for gold karat determination is the cupellation method. However, this method is not sufficiently accurate to determine gold karat in the presence of insoluble Platinum–Group Metals (PGMs), such as Ir, Ru, and Rh. In this study, for the first time, a complementary method that can be used coupled with the reference cupellation method is presented for the high...
