Abstract

Abstract: Target transformation factor analysis was used to correct spectraLINterference in inductively coupled plasma atomic emission spectrometry(ICPAES) for the determination of rare earth impurities in high purity thulium oxide. Data matrix was constructed with pure and mixture vectors and background vector. Amethod based on an error evaluation function was proposed to optimize the peak position, so the influence of the peak position shift in spectral scans on the determination was eliminated or reduced. Satisfactory results were obtained using factor analysis and the proposed peak position optimization method.

Key words: Inductively coupled plasma, Atomic emission spectrometry, Factor analysis, SpectraLINterference correction, Peak position shift
