Dispersive liquid-liquid microextraction for the determination of three cytokinin compounds in fruits and vegetables by liquid chromatography with time-of-flight mass spectrometry.
TL;DR: A novel approach for the determination of three cytokinin compounds, thidiazuron, 1,3-diphenylurea and forchlorfenuron, in fruit and vegetables samples using liquid chromatography with electrospray ionization and time-of-flight mass spectrometry (LC-ESI-TOFMS).

Determination of Brilliant Blue FCF in food and cosmetic samples by ionic liquid independent disperse liquid–liquid micro-extraction
TL;DR: In this article, a method of ionic liquid independent disperse liquid liquid micro-extraction (IL-IDLLME) coupled with UV-Visible spectroscopy was developed and applied to determination of the synthetic dye Brilliant Blue FCF (E133) in six different kinds of food and cosmetic samples, namely soft drinks, candy, jelly, kiwi fruit (Actinidia chinensis) pieces, roasted pea, ice cream, eau de toilette and shampoo.

New procedure for the control of the treatment of industrial effluents to remove volatile organosulfur compounds.
TL;DR: A new procedure for the determination of volatile organosulfur compounds in samples of industrial effluents using dispersive liquid-liquid microextraction and gas chromatography with flame photometric detection is presented.
Journal ArticleDOI
Application of dispersive liquid–liquid microextraction and reversed phase-high performance liquid chromatography for the determination of two fungicides in environmental water samples
TL;DR: Compared with other methods, DLLME is a very simple, rapid, sensitive (low limit of detection) and economical (only 5 mL volume of sample) method.

Rapid screening of water soluble arsenic species in edible oils using dispersive liquid-liquid microextraction.
TL;DR: R reverse dispersive liquid-liquid microextraction was used to extract water soluble arsenic compounds (inorganic arsenic, methylarsonate, dimethylarsinate and arsenobetaine) from the edible oils into a slightly acidic aqueous medium, and inorganic arsenic was not found in any of the samples marketed as edible oils.

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.
