Quantitative Spectrographic Analysis of Gold on Coatings over Brass

Volume 22, Number 6 (Dec. 1968) Page 790-790

Russo, Carlos Ferraro

This study was made to develop a method of quantitative analysis of gold coatings in a range between 0.010% and 0.500%. With these data, it is possible to obtain the weight of the gold coatings. In some cases we are able to find out the thickness of the gold coatings. The method uses the technique of the fixed Internal Standard. The Standard is added to the sample. Table I summarizes the equipment used and Table II indicates the operating conditions.
