Ionic-liquid-based dispersive liquid-liquid microextraction coupled with high-performance liquid chromatography for the forensic determination of methamphetamine in human urine.
TL;DR: A simple, sensitive, and environmentally friendly method based on ionic liquid dispersive liquid-liquid microextraction combined with high-performance liquid chromatography was established for the analysis of methamphetamine in human urine and has been successfully employed for the sensitive detection of a urine sample from a suspected drug abuser.

Comparison of dispersive liquid–liquid microextraction and the modified QuEChERS method for the determination of fipronil in honey by high performance liquid chromatography with diode-array detection
Débora Tomasini,Maicon R. F. Sampaio,Liziane V. Cardoso,Sergiane Souza Caldas,Ednei Gilberto Primel +4 more
TL;DR: Two methods, based on dispersive liquid-liquid microextraction (DLLME) and Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS), have been developed, validated and critically compared in order to analyze the insecticide fipronil in honey by high performance liquid chromatography coupled with diode array detection.

Liquid-Phase Microextraction in a Single Drop of Organic Solvent by Using a Conventional Microsyringe
Y. He and,Hian Kee Lee +1 more
TL;DR: In this article, two modes of liquid-phase microextraction (LPME) were developed for capillary gas chromatography, i.e., static and dynamic LPME, which involve the use of very small amounts of organic solvent in a conventional microsyringe.
