Abstract
An iterative method and apparatus for correction and compensation of analytical signals, such as spectrometric data, is provided which corrects for spectral cross-talk; compensates for spectral shift; and reduces error propagation. The method and apparatus can be applied to a multicomponent sample analysis using least squares procedure with differentiation while reducing noise propagation.
