Vortex-assisted liquid-liquid-liquid microextraction (VALLLME) technique: A new microextraction approach for direct liquid chromatography and capillary electrophoresis analysis.
A new, rapid and sensitive microextraction technique named vortex-assisted liquid-liquid-liquid microextraction (VALLLME) is proposed. The complete extraction process involves two steps. First, a vortex-assisted liquid-liquid microextraction (VALLME) procedure was used to extract the analytes from a relatively large volume of sample (donor phase) to a small volume of organic solvent (intermedia...

A green and efficient ionic liquid-based ultrasound-assisted in-situ solvent formationmicroextraction (IL-UA-ISFME) in combination with high-performance liquid chromatographyultravioletdetection (HPLC-UV) has been successfully developed for the trace determination offive selected polycyclic aromatic hydrocarbons (PAHs) in environmental water samples. In thismethod, a hydrophobic ionic liquid (1...
متن کاملVortex-Assisted Inverted Dispersive Liquid-Liquid Microextraction of Naproxen from Human Plasma and Its Determination by High-Performance Liquid Chromatography
Extraction and determination of naproxen from human plasma were performed using Vortex-Assisted Inverted Dispersive Liquid-Liquid MicroExtraction (VA−IDLLME) and High-Performance Liquid Chromatography (HPLC). The parameters affecting extraction recovery such as type and volume of extraction and disperser solvents, pH of sample solution, stirring rate, extraction time and salt addition were ...
متن کاملDevelopment of Homogeneous Liquid-Liquid Extraction in Combination with Dispersive Liquid-Liquid Microextraction Based on Deep Eutectic Solvents for the Extraction and Assessment of Phytosterols in Animal Cream Samples using Gas Chromatography Equipp
Background and Objectives: Food quality and safety control is an important part of the public health assessment of food adulteration has been a key issue in recent years. Cream is a product containing milk fat and is one of the most expensive and widely consumed edible fats, which is often targeted for cheating by mixing various vegetable oils with natural milk fats. A way to detect this type o...
متن کاملTrace Analysis of Niflumic Acid in Milk and Human Plasma by Ion-pair-based Vortex Assisted Dispersive Liquid-liquid Microextraction Combined with UV-Vis Spectrophotometry
A simple, accurate and fast vortex-assisted dispersive liquid-liquid microextraction procedure has been developed for the extractive spectrophotometric determination of niflumic acid in biological samples. The method is based on the formation of an ion association complex between niflumic acid and methylene blue. The resulting ion-pair was extracted into dichloromethane and its absorbance was m...
