摘要：

We have developed a modified Carius Tube design that permits the low-blank digestion of geological samples prior to platinum-group element analysis. The new Carius Tubes incorporate a liner of high-purity quartz glass that retains the sample and acids during the digestion procedure. This dramatically reduces the comparatively high Pt blank associated with dissolutions in conventional Carius Tubes. Using the new Carius Tube design we are able to achieve total procedural blanks for the determination of the PGE in geological samples that are at the 1-15 pg/g level for Ru, Pd, Ir and Pt. This constitutes a reduction of blank values by a factor of similar to 10-100 compared to standard NiS fire assay sample preparation techniques.
