Determination of Trace Levels of Irgarol in Estuarine Water Matrices by Bar Adsorptive Microextraction

Bar adsorptive microextraction (BAµE), using selective sorbent phases, followed by liquid desorption in combination with large volume injection—gas chromatography coupled to mass spectrometry (BAµE–LD/LVI–GC-MS), is proposed for the determination of trace levels of irgarol in estuarine water matrices. While we compared several polymers and activated carbons, one of the latter coatings showed much higher selectivity through BAµE. Assays performed...
