LC Determination of Mono-Substituted Phenols in Water Using Liquid–Liquid–Liquid Phase Microextraction

Preconcentration and Determination of Organophosphorus Pesticides in Water Samples by Graphene Oxide Nanoparticles Reinforced Hollow Fiber Solid/liquid Phase Microextraction and Gas Chromatography-flame Ionization Detector

“…The preconcentration factor in HF-SLPME is basically determined by the analyte recovery and by the phase volume of the sample and the acceptor theoretically. As the volume of the sample increases, the pre-concentration factor also increases [25][26][27] . In HF-SPME, extraction is an equilibration process, therefore the amount of analyte partitioning into the acceptor phase becomes independent of the sample volume when this volume is much higher than the product of the partition constant and the volume of the acceptor phase.…”

Optimization of a novel method for determination of benzene, toluene, ethylbenzene, and xylenes in hair and waste water samples by carbon nanotubes reinforced sol–gel based hollow fiber solid phase microextraction and gas chromatography using factorial experimental design

“…The preconcentration factor in HF-SPME is basically determined by the analyte recovery and by the phase's volume of the sample and the acceptor theoretically. As the volume of the sample increases, the pre-concentration factor also increases [21][22][23]. In HF-SPME, extraction is an equilibration process and, therefore the amount of analyte partitioning into the acceptor phase becomes independent of the sample volume when this volume is much higher than the product of the partition constant and the volume of the acceptor phase.…”

Directly suspended droplet microextraction coupled with high performance liquid chromatography: A rapid and sensitive method for acetaldehyde assay in peritoneal dialysis fluids

“…Compared with the other LPME techniques based on droplet system, like single drop microextraction, DSDME offers several advantages over traditional extraction techniques for example more flexibility in the choice of the acceptor droplet volume and stirring frequency [28,29].…”
