[Interlaboratory tests: completion of a method of aluminum assay in serum by electrothermal atomic absorption spectrometry].
After carrying out a prior analysis of published literature, the members of the SFBC trace-elements study group present an interlaboratory trial on the measurement of aluminum in serum using electrothermal atomic absorption spectrometry. The means of measurement chosen, following methods reliability criteria, was the use of a standard addition calibration of the samples diluted 1/5 in nitric acid 0.02 mol.l-1. Standard addition calibration was performed on two serums and gives acceptable results. Measurements are preferably carried out in 'tantalised' graphite tubes or pyrolytic tubes with platforms. However, when using graphite tubes, their quality must be checked because measurements can be seriously affected by poor quality tubes.
