Type of sample The method is applicable to the analysis of potable waters, ground waters, and lightly polluted surface and sea waters. 2Substance determined The method determines filterable (dissolved) and acid-soluble aluminium, 3 Range The method includes low range determination up to 100 ng/l Al with 50 mm cells and high range determi nation up to 500 |ig/l Al with 10 mm cells. The effec tive range depends on the sensitivity of the spectrometer and can be extended upwards by taking smaller test portions. 4 Limit of detection The limit of detection is 2 ng/l when cells of optical path length 50 mm and a 25 ml test portion are used. 5 Sensitivity An aluminium concentration of 100 p.g/1 gives an absorbance of about 0,20 + 0,05 optical absorption units, using a 25 ml test portion and cells of optical path length 10 mm. 6 Precision If not specified, the precision of volumes and masses mentioned in this International Standard is + 1 % of the value.
