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.
