[An effective method of mutual interference coefficients for correcting spectral interferences in routine ICP-AES for multielement analysis].
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.
