Power spectrum (PS) based analysis of multicomponent chromatograms is extended to chromatograms containing peak of different width. For Poissonian chromatograms the PS is derived both for cases where peak width and retention time are indipendent of one another and for cases of linear peak broadening. Computer generated chromatograms were used to test the derived model equations. The results obtained by simulation are explored on the basis of the theoretically derived equations, and the relevance of the results in handling practical cases is emphasized.

Abstract
Power spectrum (PS) based analysis of multicomponent chromatograms is extended to chromatograms containing peak of different width. For Poissonian chromatograms the PS is derived both for cases where peak width and retention time are indipendent of one another and for cases of linear peak broadening. Computer generated chromatograms were used to test the derived model equations. The results obtained by simulation are explored on the basis of the theoretically derived equations, and the relevance of the results in handling practical cases is emphasized.File in questo prodotto:
