Improved solvent collection system for a dispersive liquid-liquid microextraction of organochlorine pesticides from water using low-density organic solvent.
TL;DR: This method used a very small volume of a solvent of low toxicity to extract OCPs from 10 mL water samples prior to the analysis by GC, using a low-density organic solvent and an improved solvent collection system (DLLME-ISCS).

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.
