[Spectral interference correction for ICP-AES by factor analysis and a comparison with other methods].
Factor analysis method was used to correct spectral interference in inductively coupled plasma atomic emission spectrometry (ICP-AES) in the present work. The spectral overlap and structural background interferences were investigated and discussed with two real examples. Results show that the factor analysis is comparable to partial least squares (PLS) and the Kalman filtering in correcting the interferences.
