In order to extract organic micro-pollutants from surface/ground water and wastewater samples, automatic solid phase extraction is performed (Solid Phase Extractor), ensuring minimal solvents use, extraction time and also enabling the processing of 12 samples, simultaneously.
For solid samples such as flora, fauna, soil/sediment an automatic Accelerated Solvent Extractor is used (AES 300 DIONEX) which, at high pressure and temperature, performs extraction with four solvents for 24 samples simultaneously, reducing the required extraction time.
Organic micro-pollutants analysis is performed by gas chromatography with electron capture detector (Perkin Elmer Clarus 600), whose configuration allows the determination of organochlorine pesticides and polychlorinated biphenyl compounds.
