The technique consists of three steps. Initially, SbH(3) is formed by hydride generation procedure; then the analyte species in vapor form are transported to W-coil trap heated at 370 degrees C. Following the preconcentration step, the trap is heated to 895 degrees C; analyte species are revolatilized and transported to the flame-heated quartz atom cell where atornization and the formation of signal take place. The experimental parameters were optimized both for trap and no-trap studies. The most important experimental parameters are concentrations of HCI and NaBH4 solutions. H2 and At gas flow rates. and collection and revolatilization temperatures of W-coil. Accuracy was tested using a certified reference material, waste water EU-L-1. Limit of detection for the system is 16 ng 1- 1 using a sample of 36 ml collected in 4.0 min. Enhancement factor in sensitivity was 17. (c) 2008 Elsevier B.V.
