Xg. Shao et al., QUANTITATIVE-DETERMINATION OF THE COMPONENTS IN OVERLAPPING CHROMATOGRAPHIC PEAKS USING WAVELET TRANSFORM, Analytical chemistry, 69(9), 1997, pp. 1722-1725
A novel application af the wavelet transform in retrieving the separat
e signals from overlapping chromatographic peaks and quantitative dete
rmination of the components in the overlapping chromatograms is descri
bed, The signals can be very easily separated by decomposing an overla
pping chromatographic peak into localized contributions according to t
heir frequency, and quantitative calculation can be done by studying t
he contributions of higher frequency. Overlapping peaks of two- and th
ree-component mixtures were investigated by the method, and the result
s slow excellent correlations between peak areas of the retrieved sign
als and the concentrations for all of the components.
