所述方法的原理是调节待分析的提取液，使用钼酸铵和还原溶液显影蓝色硅钼酸盐络合物，通过分子吸收光谱仪使用10mm光学单元在800nm测量所得彩色络合物的光密度。测量硅的浓度，以其氧化物SiO2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 conditioning the extract solution to be analyzed, developing the blue silicomolybdate complex using ammonium molybdate and a reducing solution, measuring the optical density of the resulting colour complex by means of a molecular absorption spectrometer at 800 nm using 10 mm optical cells. Measures the concentrations of silicon, expressed as its oxide SiO2. 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.
