Methods are described for the determination of aluminium in serum and in diluted urine by means of graphite furnace atomic absorption spectrometry. For the analysis of serum, thermal decomposition of the sample in the furnace, using a ramp charring program, was found to be necessary in order to eliminate the organic material. The precision of the method was 10%. For urine the relative deviation was 9%. The precision was markedly improved by the use of an automatic sample injector (5.3%). Since large contamination problems make the determination of Al at the parts per billion (ppb) level very difficult, special attention was paid to the precautions to be taken in order to avoid external aluminum contamination.
描述了通过石墨炉原子吸收光谱法测定血清和稀释尿液中铝的方法。对于血清分析，发现为了消除有机物质，在炉中使用升温炭化程序对样品进行热分解是必要的。该方法的精密度为10%。对于尿液，相对偏差为9%。使用自动进样器可显著提高精密度（5.3%）。由于大量的污染问题使得在十亿分之一（ppb）水平测定铝非常困难，因此特别注意了为避免外部铝污染而应采取的预防措施。
