| Abstract | The coupling of flow injection-hydride generation with in situ concentration in a graphite furnace is demonstrated to be an effective method for the determination of arsenic in the presence of interferent suppressors. The trapping of arsine on a deposit of reduced Pd is shown to be 100% efficient. The addition of L-cysteine permits full recovery of the As signal in the presence of 100 μg amounts of Ni or Pt. Thiourea is effective at reducing interferences from 100 μg Au, Ni or 10 μg Pd. Increased amounts of Pd or peak area calibration can reduce interferences that occur in the graphite furnace due to other hydride forming elements. A characteristic mass of 10.6 pg and a limit of detection of 36 pg was obtained. |
