Kinetic electro membrane extraction under stagnant conditions--fast isolation of drugs from untreated human plasma.

Lars Erik Eng Eibak, +4 more
- 30 Jul 2010 - 
TL;DR: Electro membrane extraction from plasma combined with LC-MS provided limits of quantification, linearity, repeatability, and linearity in the range 1-1000ng/ml with r(2)-values of 0.998-0.999, but EME required substantially less time than SPE.
Journal ArticleDOI

Liquid-phase microextraction combined with capillary electrophoresis, a promising tool for the determination of chiral drugs in biological matrices.

Solveig Norheim Andersen, +3 more
- 19 Jul 2002 - 
TL;DR: The method was validated and successfully applied to determine R- and S-mianserin in plasma samples from seven patients treated with mianserserin, indicating that LPME-CE is a promising combination for analysis of racemic drugs present in low concentrations in biological matrices.
Journal ArticleDOI

Recent developments in electromembrane extraction

Astrid Gjelstad, +2 more
- 22 Aug 2013 - 
TL;DR: Electromembrane extraction (EME) is a liquid-phase microextraction technique intended for analytical sample preparation as mentioned in this paper, where charged analytes are extracted in an electrical field, from the aqueous sample solution, through a supported liquid membrane and into an acceptor phase.
Journal ArticleDOI

Stereospecific determination of citalopram and desmethylcitalopram by capillary electrophoresis and liquid-phase microextraction.

Solveig Norheim Andersen, +5 more
- 19 Sep 2003 - 
TL;DR: The validated method was successfully applied to simultaneous determination of enantiomers concentrations of CIT and DCIT in plasma samples from nine patients treated with racemic citalopram, confirming LPME-CE as a suitable and promising tool for enantiomeric determination of chiral drugs and metabolites in biological matrices.
Journal ArticleDOI

Feasibility of a liquid‐phase microextraction sample clean‐up and liquid chromatographic/mass spectrometric screening method for selected anabolic steroid glucuronides in biological samples

Tiia Kuuranne, +6 more
- 01 Jan 2003 - 
TL;DR: The LPME/LC/MS/MS method was fast and reliable, offering acceptable reproducibility and linearity with detection limits in the range 2-20 ng ml(-1) for most of the selected AAS glucuronides.
