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.
