Preconcentration and determination of pyrethroid insecticides in water with ionic liquid dispersive liquid-phase microextraction in combination with high performance liquid chromatography
TL;DR: The experimental results indicated that the longer alkyl chain length of ILs resulted in better extraction efficiency, and 1-octyl-3-methylimidazolium hexafluorophosphate [C8MIM] [PF6] was the best one for extraction of the target analytes.

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.
