GB/T 24579-2009 is the English-translated version of 酸浸取 原子吸收光谱法测定多晶硅表面金属污染物.
GB/T 24579-2009 — This standard specifies the use of acid leaching from the surface of the polycrystalline silicon pieces of metal impurities. And graphite furnace atomic absorption quantitative detection of trace metal impurities on the polysilicon block surface analysis methods.
This standard applies to the alkali metal, alkaline earth metal and the first series of transition elements such as sodium, zinc detection, Nickel, aluminum, iron, chromium.
This standard applies to all kinds of rods, blocks, grain, sheet-shaped multi- product or single crystal silicon surface to detect metal contaminants. Since the block, pieces or grains of irregular shape.
Area is difficult to accurately determine. Calculated according to the sample weight. Weight of the sample used is 50g ~ 300g, LOD tied to 0.
