Deconvolution studies of multicomponent systems in GAS chromatography

Abstract

The objective of the present study is to propose a method of deconvolution in highly overlapped chromatograms and to show the applicability of the technique to real chromatograms. The method is an extension of the previously reported work by Jung et al. which involves the solution of the cubic or quartic equation of $\tau$. The deconvolution procedure is performed adopting Marquardt formalism. The study was carried out on the various effects of the degree of resolution, the different peak sizes, the random noise level, and constant peak shape on the deconvolution of overlapped peaks. In all cases the area factors, A``s, which were linearly proportional to concentrations were reproducible within 2.0\% in present technique at the noise value up to 1.0\%. And the applicability of the technique to quantitative analysis has been discussed in detail.
