Directly suspended droplet microextraction in combination with microvolume UV-vis spectrophotometry for determination of phosphate.
Francisco Pena-Pereira,Noelia Cabaleiro,Inmaculada de la Calle,Marta Costas,Sandra Gil,Isela Lavilla,Carlos Bendicho +6 more
TL;DR: A miniaturized methodology for the determination of phosphate in waters has been developed by combining directly suspended droplet microextraction (DSDME) with microvolume spectrophotometry and was successfully applied to the determined of dissolved reactive phosphorus in different freshwater samples.

Dispersive liquid–liquid microextraction coupled to liquid chromatography for thiamine determination in foods
TL;DR: The DLLME procedure coupled to liquid chromatography (LC) with fluorimetric detection was evaluated for the preconcentration and determination of thiamine (vitamin B1) and the selectivity of the method was judged from the absence of interfering peaks at theThiamine elution time for blank chromatograms of unspiked samples.

Ultrasound-assisted analytical emulsification-extraction
TL;DR: In this article, the usefulness of ultrasound for improving steps in analytical chemistry has been widely demonstrated in the past decade, and potential uses with special emphasis on the achievements and the weak points of the present research are discussed.

Analytical chemistry, formation, mitigation, and risk assessment of polycyclic aromatic hydrocarbons: From food processing to in vivo metabolic transformation.
TL;DR: The levels of PAH contamination in food are mainly influenced by processing procedures and cooking methods, and they could be attenuated by modifying cooking procedures and adding antioxidant-rich marinades.

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.
