Book Description
Precious metal analysis of fresh reforming catalysts are typically performed by both the catalyst manufacturer and buyer to arrive at a financial settlement on the quantity of metal in each lot of commercial catalyst: Traditional assay methods involve a variety of fire assay or wet chemical acid digestion schemes coupled with gravimetric, colorimetic, or titrimetric measurement for precious metals. Methods must have sufficient precision and accuracy to afford interlaboratory agreement of within one half of one percent relative between the catalyst supplier and purchaser. To meet this requirement many laboratories rely on classical methods. Unfortunately these procedures are labor intensive and time consuming.

Book Description
This paper reviews the current performance and application of analytical methods used for the determination of the platinum-group metals. The techniques reviewed include fire assay, emission spectroscopy, X-ray fluorescence spectroscopy, atomic-absorption spectroscopy, and mass spectrometry. Tables are included to indicate precision and limits of detection. Although applications vary from one laboratory to another, some general observations are made regarding the suitability of the different techniques to different types of samples.

Book Description
A handbook of practical techniques for professionals and students involved in the analysis of precious metals, either for exploitation or for contaminants. While most of the literature covers single techniques, it collects information on methods of analysis in a single source. After introducing the elements, basic techniques of analysis and the physical and chemical properties of precious metals are discussed. Also provides techniques for sampling for precious metals in ores, minerals, concentrates, rock, water, and biological, biogeochemical, and industrial samples.
