Journal ArticleDOI
Liquid-phase microextraction combined with liquid chromatography-mass spectrometry. Extraction from small volumes of biological samples
TL;DR: In this paper, the combination of liquid phase microextraction (LPME) with LC-MS using electrospray ionization for high sensitivity was described, and the results were qualitatively investigated for matrix effects using a post-column infusion system.
Journal ArticleDOI
Parallel electromembrane extraction in the 96-well format.

TL;DR: The aim of the present investigation was to demonstrate the potential of electromembrane extraction as a high throughput sample preparation platform and hopefully to increase the interest for EME in the bioanalytical field to solve exisiting and novel analytical challenges.
Journal ArticleDOI
Supported liquid membranes in hollow fiber liquid-phase microextraction (LPME)--practical considerations in the three-phase mode.
TL;DR: Reuse of hollow fibers was found to suffer from matrix effects due to built-up of analytes in the SLM, whereas washing of the hollow fibers in acetone was beneficial in terms of recovery, especially for the extraction of the most hydrophobic substances.
Journal ArticleDOI
Exhaustive extraction of peptides by electromembrane extraction.
TL;DR: This fundamental work illustrates for the first time the possibility of exhaustive extraction of peptides using electromembrane extraction (EME) under low system-current conditions and finds increasing the SLM volume from 5 to 10 μL was found to be beneficial for stable and efficient EME.
Journal ArticleDOI
Fundamental studies on the electrokinetic transfer of net cationic peptides across supported liquid membranes.
TL;DR: By the application of an electrical potential difference (25 V), 37 different peptides were extracted from 500 μL aqueous sample through a supported liquid membrane (SLM) impregnated in the walls of a porous hollow fiber, and into 25 μL acceptor solution present inside the lumen of the fiber.
