摘要
光电直读光谱法评价分析低含量元素的重要依据是 :检测限、精密度、稳定性。通过对光电直读光谱法测量纯金属中痕量元素分析条件的研究 ,发现被测元素的检出限主要取决于所选择的分析谱线及放电类型 ,与参比线基本无关 ;被测元素的测量精密度及稳定性主要取决于分析线对 (分析谱线 参比线 )及放电类型。这个规律可用于选择最佳测量条件 ,快速准确地测定纯金属中痕量元素。
The important factor for trace concentration element analysis by optical emission spectrometry is detection limit,RSD,stability Through study on analytical parameters of trace element in pure metal, it is found that the detection limit of element mainly depends on the choosed analytical line and discharge type but bears no relation to referenceRSD and stability of analysis depend on analytical line pair(analytical line/reference line)and discharge type The best analytical parameter will be selected to make quick and accurate analysis with this principle
