所述方法的原理是将提取物溶液喷射到发射或吸收光谱仪的燃烧器的火焰中，如果需要添加光谱化学缓冲溶液，或者喷射到过滤火焰光谱仪的火焰中而不添加该缓冲溶液。对于FES和FAAS，分别使用589.0 nm和766.5 nm处的谱线，并与参考溶液的测量值进行比较，对于火焰过滤器光谱仪，使用特定的过滤器。测量钠和钾的浓度，以它们的氧化物Na2O和K2O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。
The principle of the method specified is spraying the extract solution into the flame of the burner of an emission or absorption spectrometer, if necessary with the addition of a spectrochemical buffer solution, or into the flame of a filter flame spectrometer without this addition. For FES and FAAS, the lines at 589,0 nm and 766,5 nm, respectively, are used and compared with the measurements of reference solutions, for a flame filter spectrometer, the specific filters are used. Measures the concentrations of sodium and potassium, expressed as their oxides Na2O and K2O. Applies to the analysis of extract solutions obtained from any kind of glass or glassware.
