Dual-hollow fiber microextraction (dual-HFμE) - application for monitoring trace levels of organochlorine pesticides in real matrices

In this contribution, the features and the advantages of the modified hollow fibre microextraction (HFµE) technique are discussed, by using two membranes (dual-HFµE) per sample, loaded with convenient organic solvents. The new approach proposed combined with micro-liquid desorption followed by large volume injection-gas chromatography-mass spectrometry operating in the selected-ion monitoring acquisition mode, [dual-HFμE-μLD/LVI-GC-MS(SIM)], was...
