Aerosol deposition-carbon furnace atomisation for simultaneous multi-element atomic absorption spectrometry

摘要: A commercially available aerosol deposition-carbon furnace atomiser was used with a simultaneous multi-element atomic absorption continuum source (SIMAAC) spectrometer. The optimum deposition temperature 120 ± 20 °C. Within this range, no difference observed for the behaviour of standards in 0.5 and 5% nitric acid. analytical signal linear respect to time. signals (both peak height area) all 16 elements were independent atomisation above threshold (characteristic each element). compromise dictated by least volatile element. Detection limits characteristic concentrations dependent on Simultaneous determination nine NBS SRM 1643a, acidified water, well-characterised fruit juices yielded accurate results.
