Extração sortiva em barra de agitação para análise de fármacos em fluidos biológicos
(Sociedade Brasileira de Química, 2008)
A novel solventless sample preparation, stir-bar sorptive extraction (SBSE), for extraction, and sample enrichment of organic compounds from biological fluids, is described in this manuscript from principle to applications. ...
Simultaneous analysis of parabens in cosmetic products by stir bar sorptive extraction and liquid chromatography
(WILEY-V C H VERLAG GMBH, 2010)
A sensitive and precise stir bar sorptive extraction (SBSE) combined with LC (SBSE/LC) analysis is described for simultaneous determination of methyl, ethyl, propyl, and butyl parabens in commercial cosmetic products in ...
Polydimethylsiloxane/polypyrrole stir bar sorptive extraction and liquid chromatography (SBSE/LC-UV) analysis of antidepressants in plasma samples
(ELSEVIER SCIENCE BV, 2009)
A new polymeric coating consisting of a dual-phase, polydimethylsiloxane (PDMS) and polypyrrole (PPY) was developed for the stir bar sorptive extraction (SBSE) of antidepressants (mirtazapine, citalopram, paroxetine, ...
Determination of fluoxetine in plasma by gas chromatography-mass spectrometry using stir bar sorptive extraction
(ELSEVIER SCIENCE BV, 2008)
This article presents a method employing stir bar sorptive extraction (SBSE) with in situ derivatization, in combination with either thermal or liquid desorption on-line coupled to gas chromatography-mass spectrometry for ...
Pesticide residue determination in surface waters by stir bar sorptive extraction and liquid chromatography/tandem mass spectrometry
(2009)
In this stir bar sorptive extraction (SBSE) method, 16 pesticides were extracted from surface water samples by sorption onto 1 mm polydimethylsiloxane layer coated on a 10-mm-length stir bar magnet. After liquid desorption ...
Pharmaceutical compounds determination in water samples: Comparison between solid phase extraction and STIR Bar sorptive extraction
(Sociedad Chilena de Quimica, 2017)
A variety of organic compounds and their metabolites used in pharmaceutical and personal care products (PPCP´s) are continuously introduced into the environment by domestic or industrial wastewater. Solid phase extraction ...
Development of a new stir bar sorptive extraction coating and its application for the determination of six pesticides in sugarcane juice
(WILEY-BLACKWELL, 2011)
In this article, a novel polydimethylsiloxane/activated carbon (PDMS-ACB) material is proposed as a new polymeric phase for stir bar sorptive extraction (SBSE). The PDMS-ACB stir bar, assembled using a simple Teflon (R)/glass ...
A novel HS-SBSE system coupled with gas chromatography and mass spectrometry for the analysis of organochlorine pesticides in water samples
(WILEY-V C H VERLAG GMBH, 2008)
A methodology to analyze organochlorine pesticides (OCPs) in water samples has been accomplished by using headspace stir bar sorptive extraction (HS-SBSE). The bars were in house coated with a thick film of PDMS in order ...
