ABSTRACT:
A spectral interval excited by ICP-ES containing expected lines is modeled from wavelength calibration information and from spectra of model components. A sample is then excited and fit to the data with concurrent observation of wavelength calibration and a linear least squares fit obtained with analysis of residuals to determine presence of unexpected spectral features which, if present, provide additional model components for an iterative fitting.
