所述方法的原理是将待分析的提取溶液中的铝与铬天青S络合，通过分子吸收光谱仪使用10mm光学池在545nm测量所得溶液的光密度。测量铝的浓度，以其氧化物Al2O3表示。适用于从任何种类的玻璃或玻璃器皿中获得的提取液的分析，包括实验室和制药器皿、食品和饮料包装器皿、餐具和厨房器皿。
The principle of the method specified is complexing of the aluminium in the extract solution to be analyzed with chromazurol S, measuring the optical density of the resulting solution by means of a molecular absorption spectrometer at 545 nm using 10 mm optical cells. Measures the concentration of aluminium, expressed as its oxide Al2O3. Applies to the analysis of extract solutions obtained from any kind of glass or glassware including laboratory and pharmaceutical ware, food and drink packaging ware, tableware and kitchenware.
