✦ Synopsis

The operating parameters for a high current caesium sputter source have been modified so that stable beams of anions can be obtained from natural non-conducting samples. This technique has been applied to the analysis of gold and platinum group elements in silicate matrices, particularly olivines. The handling of interferences resulting from the large number of molecular ions produced in such a target, and the effect of differences in the matrices of reference materials are discussed.

Ten kimberlites from various localities in South Africa have been analysed for all of the platinum-group elements (PGEs) and gold using a nickel sulphide fire-assay preconcentration followed by neutron activation analysis (NAA). Problems encountered during the analysis of these samples prompted a ra
