相互干扰系数法校正ICP-AES多元素同时分析的光谱干扰

AN EFFECTIVE METHOD OF MUTUAL INTERFERENCE COEFFICIENTS FOR CORRECTING SPECTRAL INTERFERENCES IN ROUTINE ICPAES FOR MULTIELEMENT ANALYSIS

提出了一种相互干扰系数法校正ＩＣＰＡＥＳ多元素同时分析的光谱干扰方法。该方法把分析对象视为所有组分之间都相互关联的体系，并选择严密的数学模型来校正复杂组分间的相互干扰。

An effective method was used to correct spectral interferences in routine ICPAES for multielement analysis.In this method,all the components in an analysed object were considered to be related to each other,a strict mathematical model was applied and the mutual interference coefficients obtained from the usual artificial samples were replaced by those from natural standard samples which had the some matrix as the samples to be analysed.These mutual interference coefficients were used to correct the analysis data of GSD samples,and the results were mostly more precise than those corrected by the coefficients obtained from artificial samples.The correcting speed of this method is quick enough to satisfy the requirement of realtime correcting of analysis.
