Identification and determination of chlorinated paraffins using multivariate evaluation of gas chromatographic data

► Chromatograms of chlorinated paraffins were evaluated by principal component analysis (PCA). ► PCA of standards yield calibration curves with different orientation in multivariate space. ► More than one chloroparaffin formulation was found in food waste from Sweden. ► The chloroparaffin source was the food waste itself, not the collection chain.
