A method for the determination of aluminum in beer, has been collaboratively tested. The method tested relies on atomic absorption spectrometry with atomization in a graphite furnace. Five pairs of beers, with concentrations ranging from 96 to 1000 μg/litre, were analysed by eleven laboratories. The repeatability (r 95 ) values ranged from 10 to 69 μg/l, and the reproducibility (R 95 ) values ranged from 70 to 465 μg/l,. A second collaborative trial with a slightly different method protocol gave no improvement. Due to the high reproducibility values the method was not adopted for inclusion in Analytica‐EBC.
