Determination of pesticides and metabolites in wine samples by HPLC-DAD and second-order calibration methods

The second-order calibration models PARAFAC and the recently introduced BLLS were applied to several chromatographic-diode array detection systems, where overlap of interferences with the compounds of interest was observed, making the determination and resolution of the analytes possible. In this wo...
