✦ Synopsis

The determination of zinc in aluminium metal by sequential metal vapour elution analysis (column temperature > 1650 K) with argon as carrier gas and with atomic absorption spectrometric detection is described. The column was made of a molybdenum capillary tube (250 mm X 1.22 mm i.d.). The zinc vapour was separated from Al, Cu, Fe, Mg, Si and Ti metal vapour at the column temperature of 1650 K. The absolute detection limit was 12 pg (12 ng g-t). The relative standard deviation for the determination of zinc in ahuninium metals was 4.9-13%. The results were in good agreement with those obtained by a spectrometric method and a certified value.
