Dispersive liquid–liquid microextraction of quinolones in porcine blood: Optimization of extraction procedure and CE separation using experimental design
(Wiley VCH Verlag, 2016-10)
A dispersive liquid–liquid microextraction procedure was developed to extract nine fluoroquinolones in porcine blood, six of which were quantified using a univariate calibration method. Extraction parameters including type ...
Capabilities of several phosphonium ionic liquids for arsenic species determination in water by liquid-liquid microextraction and electrothermal atomic absorption spectrometry
(Royal Society of Chemistry, 2015)
The capabilities of several phosphonium-ionic liquids (PILs) to form ion-pairs with a complex obtained by reaction of arsenate species with molybdate were evaluated. Phosphonium-ILs containing the tetradecyl(trihexyl)phosphonium ...
Room temperature ionic liquid-based microextraction for vanadium species separation and determination in water samples by electrothermal atomic absorption spectrometry
(Elsevier Science, 2009-04)
A simple microextraction technique based on room temperature ionic liquids (RTILs) for trace V(IV) and V(V) species separation and preconcentration in water samples was developed in this work. Vanadium species microextraction ...
Determination of fluoxetine and norfluoxetine enantiomers in human plasma by polypyrrole-coated capillary in-tube solid-phase microextraction coupled with liquid chromatography-fluorescence detection
(ELSEVIER SCIENCE BV, 2009)
A sensitive, selective, and reproducible in-tube polypyrrole-coated capillary (PPY) solid-phase microextraction and liquid chromatographic method for fluoxetine and norfluoxetine enantiomers analysis in plasma samples has ...
A microextraction procedure based on an ionic liquid as ion-pairing agent optimized using a design of experiments for chromium species separation and determination from water samples
(Royal Society of Chemistry, 2013-07-19)
A microextraction methodology based on a room temperature ionic liquid (IL) as an ion-pairing reagent for determination of trace Cr(III) and Cr(VI) species is proposed. First, an ion-pair was formed between Cr(VI) species ...
Faster and simpler determination of chlorophenols in water by fiber introduction mass spectrometry
(Elsevier Science BvAmsterdamHolanda, 2008)
Taints: analysis and identification
(Elsevier, 2016)
Taints and off flavors deteriorate the quality and acceptability of food products, being one of the most common reasons for consumer rejection of a certain food. Occurrence of taints causes significant financial loss to ...
Chiral HPLC analysis of venlafaxine metabolites in rat liver microsomal preparations after LPME extraction and application to an in vitro biotransformation study
(SPRINGER HEIDELBERG, 2010)
A three-phase LPME (liquid-phase microextraction) method for the enantioselective analysis of venlafaxine (VF) metabolites (O-desmethylvenlafaxine (ODV) and N-desmethylvenlafaxine (NDV) in microsomal preparations is described ...
