Einige besondere Bestimmungsanhalte,in representative samples (50g). The procedure is based on the established nickel sulphide bead method, with lithium tetraborate in the flux and a fusion temperature of 1000°C. When the analytical technique was tested by measuring the PGE in reference materials SARM 7 and PTC-1, the data agreed with

These factors have resulted in the need for an analytical method offering . of a . allied with an . technique. For many years these criteria were satisfied by fusion of large sample aliquots followed by gravimetric measurement of the various

This X-ray film offers equivalent resolution to the nuclear research plates but is less easily damaged during handling and both reduces the cost and increases

Pathologie des Scheideninhalts. Fluorsolution is necessary for mobilization and differentiation in oxide zones. Previous suggestions concerning this complex chemistry involving chloride ion are applicable only in very unusual circumstances. It is clear that the natural ligand set available for complex formation is severely restricted.

One method for presenting noble metal, Ni and Cu data focuses on the sulphide control by recalculating the data to 100% sulphides and presenting the data chondrite normalized. The relative importance of the influence of sulphides, chromite, olivine and PGM on the noble metals, Ni
