DETERMINATION OF ALUMINUM IN BEER BY GF-AAS

A method for the determination of aluminum in beer, has been collabora tively tested. The method tested relies on atomic absorption spectrome try with atomization in a graphite furnace. Five pairs of beers, with concentrations ranging from 96 to 1000 mug/litre, were analysed by ele ven laboratories. The repeatability (r95) values ranged from 10 to 69 mug/l, and the reproducibility (R95) values ranged from 70 to 455 mug/ l,. A second collaborative trial with a slightly different method prot ocol gave no improvement. Due to the high reproducibility values the m ethod was not adopted for inclusion in Analytica-EBC.
