A new rotating-disk sorptive extraction mode, with a copolymer of divinylbenzene and N-vinylpyrrolidone trapped in the cavity of the disk, used for determination of florfenicol residues in porcine plasma
(Microextraction Techniques, 2014)
A novel extraction approach was developed based
on rotating-disk sorptive extraction (RDSE). In this approach
the rotating-disk extraction device consists of a Teflon disk,
with a cavity that is loaded with a commercial ...
Volatile profile characterisation of Chilean sparkling wines produced by traditional and Charmat methods via sequential stir bar sorptive extraction
(Elsevier, 2016-09)
The volatile compositions of Charmat and traditional Chilean sparkling wines were studied for the first time. For this purpose, EG-Silicone and PDMS polymeric phases were compared and, afterwards, the most adequate was ...
Recent developments in the analysis of musty odour compounds in water and wine: A review

Determination of crystal violet in water by direct solid phase spectrophotometry after rotating disk sorptive extraction
(2013)
The microextraction of crystal violet (CV) from water samples into polydimethylsiloxane (PDMS) using the rotating disk sorptive extraction (RDSE) technique was performed. The extracting device was a small Teflon disk that ...
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 ...

BTEX: Desenvolvimento de barras de extração sortiva, determinação em efluente hospitalar e degradação por meio de fotocatálise heterogênea com TiO2 suportado em polímeros
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2012-02-24)
In this work were developed low cost bars of sorptive extraction, using commercial adhesive based on polydimethylsiloxane (PDMS) for the preconcentration and determination of benzene, toluene, ethylbenzene and xylene (BTEX) ...
Analytical methods for determination of cork-taint compounds in wine
(Elsevier, 2012-07)
Cork taint is considered a major organoleptic defect in wine, producing a moldy aroma. Haloanisoles are the main compounds responsible, although there are other analytes cause the same problem. Occurrence of cork taint ...
Determination of sunscreen compounds in water samples by silicone rod extraction
(Sociedad Chilena de Quimica, 2013)
Silicone rod extraction (SR) is a siloxane-based methodology for the extraction of organic pollutants from aqueous samples with similar principle extraction as the stir bar sorptive extraction (SBSE). In this study the SR ...
