| Résumé | Efficient trapping of the volatile hydrides of As, Sb, Se, Bi and Sn on μg masses of Pd and other platinum group metals (PGM) reduced in the graphite furnace occurs at a relatively low temperature (200°C). Analytical figures of merit are improved over hydride trapping on the bare tube wall. Conditions are established for multielement sequestration. Absolute limits of detection (3σ) range between 8 pg (Se) and 43 pg (As). The catalytic reactivity of PGM's promotes low temperature deposition of the hydrides by dissociative chemisorption. Thermal desorption of all analytes from the PGM's is first order. Arrhenius energies were used to characterize all analyte-substrate interactions. |
