An example of chlorinated paraffins (SCCPs, MCCPs, and LCCPs) patterns in sewage sludge sample S2. For each chlorinated paraffin group (SCCPs, MCCPs, and LCCPs) the measured pattern is given (A, C, E) and the reconstructed pattern based on deconvolution of the technical chlorinated paraffin mixtures (B, D, F). Deconvolution of the SCCP pattern in the sewage sample was performed with the 51.5% Cl, 55.5% Cl, and 63% SCCP standards, for the deconvolution of the MCCP pattern the 42% Cl, 52% Cl, and 57% Cl MCCP standards and for the deconvolution of the LCCP pattern the 36% Cl and 49% CL LCCP standards were used. The goodness of fit (R²) for the deconvolution is also given.
