Liquid-Phase Microextraction in a Single Drop of Organic Solvent by Using a Conventional Microsyringe
Two modes of liquid-phase microextraction (LPME) were developed for capillary gas chromatography. Both methodologies, i.e., static LPME and dynamic LPME, involve the use of very small amounts ofExpand
Developments in single-drop microextraction.
This review focuses on single-drop microextraction in its recent developments in its various guises, and its applications when used in combination with different analytical techniques, such as gas chromatography, high-performance liquid chromatography and electrothermal atomic absorption spectrometry.

Effect of Cooking on the Loss of Persistent Organic Pollutants from Salmon
Losses of POPs were significantly and linearly correlated with the losses of lipid during cooking, suggesting removal of lipids is the critical factor for POPs reduction in cooked fish. Expand
Hollow fiber-protected liquid-phase microextraction of triazine herbicides.
The results demonstrated that hollow fiber-protected LPME was a fast, accurate, and stable sample pretreatment method that gave very good enrichment factors for the extraction of triazine herbicides from aqueous or slurry samples. Expand
Domestic Water Contamination in Rapidly Growing Megacities of Asia: Case of Karachi, Pakistan
The development of essential services including water and sanitation in many megacities of the economically developing countries of Asia cannot keep pace with their rapidly growing population andExpand
Environmental and bioanalytical applications of hollow fiber membrane liquid-phase microextraction: a review.
Important applications of LPME are reviewed with special focus on bioanalytical and environmental chemistry, and a new possible direction is covered namely electromembrane extraction, where analytes are extracted through the SLM and into the acceptor phase by the application of electrical potentials.

Analysis of endocrine disrupting alkylphenols, chlorophenols and bisphenol-A using hollow fiber-protected liquid-phase microextraction coupled with injection port-derivatization gas
Hollow fiber LPME was a rapid, simple and efficient technique for APs, CPs and BPA, and provided a good alternative to SPME and LLE and was applied to monitor Singapore coastal water samples. Expand
Headspace liquid-phase microextraction of chlorobenzenes in soil with gas chromatography-electron capture detection.
High-LPME was shown to be an inexpensive, fast, and simple sample preparation method for volatile compounds because of the very small space within the microsyringe barrel and the fast equilibrium between gaseous analytes and organic solvent film. Expand
Low-density solvent-based solvent demulsification dispersive liquid-liquid microextraction for the fast determination of trace levels of sixteen priority polycyclic aromatic hydrocarbons in
For the first time, the low-density solvent-based solvent demulsification dispersive liquid-liquid microextraction was developed for the fast, simple, and efficient determination of 16 priorityExpand
