Successive Approximation Correction Method for Interelement Interferences in ICP-AES

Abstract

Abstract: Various interelement interferences usually exist in the analysis of complex, multi- component samples by ICP-AES.The problem is how to look for an ideal course to correct them. Anew method named "Successive Approximation Correction Method" (SACM) is advanced in this paper. SACM is based on K-coefficient correction method, and can be described with the equation Good results, whether major or trace elements, can be gained by the use of SACM. In the article SACMis proven, checked and evaluated.

Key words: Inductively coupled plasma, Atomic emission spectrometry, Interelement interference, Successive approximation correction method
