Mycotoxins in cereals and related foodstuffs: A review on occurrence and recent methods of analysis
TL;DR: For the first time a review is done about mycotoxins occurrence in cereals and derived products published in the last years, together with the recent improvements regarding methods for their quantification.
Journal ArticleDOI
Determination of four heterocyclic insecticides by ionic liquid dispersive liquid-liquid microextraction in water samples.
TL;DR: A novel microextraction method combining high-performance liquid chromatography with diode array detection (HPLC-DAD) was developed for the determination of insecticides in water samples, and the ionic liquid was used instead of a volatile organic solvent as the extraction solvent.
Journal ArticleDOI
Green aspects, developments and perspectives of liquid phase microextraction techniques.
TL;DR: The possible use of novel, non-toxic extracting agents, inter alia, ionic liquids, coacervates, surfactant solutions and reverse micelles in the liquid phase microextraction techniques has been evaluated in depth.

Air-assisted liquid–liquid microextraction method as a novel microextraction technique; Application in extraction and preconcentration of phthalate esters in aqueous sample followed by gas chromatography–flame ionization detection
TL;DR: Under the optimum extraction conditions, the AALLME method showed low limits of detection and quantification and some aqueous samples were successfully analyzed using the proposed method and three analytes, DIBP, DNBP and DEHP, were determined in them at ng mL(-1) level.

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.
