A procedure for the determination of several coplanar and non coplanar PCBs in ash samples is described. Analytes were extracted from the samples using dimethylsulfoxide (DMSO) under the action of a microwave field, and then they were concentrated on a PDMS-DVB solid-phase microextraction (SPME) fibre using the headspace mode, after water dilution of the DMSO extract. Determinations were carrie...

The aim of the study was to carry out a the laboratory diagnosis of fetal drug exposure. We focused on the analysis of meconium, as a specimen widely accepted for this purpose. In the preliminary study on meconium samples spiked with methamphetamine or morphine we tested the conditions for homogenization and isolation. Emit was used as a screening method and two dimensional HPTLC, GC/ECD, NPD a...

Four commonly applied extraction techniques for organochlorine pesticides, microwave-assisted extraction (MAE), accelerated solvent extraction (ASE), quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction and ultrasonic solvent extraction, were applied on soil samples in order to evaluate their performances. The extracts were analyzed by GC-ECD and confirmed by GC-MS/MS. The MAE ...
