New methodology for determination of gold and precious metals using the Agilent 4100 MP-AES
نویسنده
چکیده
The accurate and precise determination of gold and other precious metals (PMs) is a vital task for companies involved in PM production and the contract or service laboratories that support them. This might involve the processing of hundreds of samples typical of exploration and mining activities, or supplying the quality control assay of the fi nal product from PM producers or recyclers. PMs are also produced as a by-product of copper or nickel processing.
