Dynamic single‐drop microextraction (SDME) was automatized employing an Arduino‐based lab‐made Cartesian robot and implemented to determine parabens in wastewater samples in combination with liquid chromatography–tandem mass spectrometry. A dedicated Arduino sketch controls the auto‐performance of all the stages of the SDME process, including syringe filling, drop exposition, solvent recycling, and...
A fast and environment‐friendly analytical method was implemented to determine multiclass pesticides in river sediments. Twenty‐three pesticides—organochlorine pesticides, organophosphorus pesticides, and triazines—were extracted via matrix solid‐phase dispersion (MSPD) and analyzed by gas chromatography–tandem mass spectrometry (GC–MS/MS). Florisil demonstrated excellent analytes uptake capability...
