A Review of Stir Bar Sorptive Extraction

Possibilities of utilization of modern sample preparation methods for gas chromatographic analysis of beverages and especially beer. Part II. - Stir Bar Sorptive Extraction.

“…Všechny tyto parametry se musí při konkrétní aplikaci optimalizovat. Po skončení extrakce se pomocí pinzety míchací tyčinka vyndá a opláchne se pable of extracting and concentrating compounds from liquid matrices without the use of solvents [5,6].…”

“…The technique was commercialized by Gerstel (Mülheim, Germany) under the name Twister. SBSE represents procedure ca-umožňující extrakci a zakoncentrování látek z kapalných matric bez použití rozpouštědel [5,6].…”

Static Headspace Extraction with Compounds Trapping for the Analysis of Volatile Lipid Oxidation Products

“…Nowadays, SPME has been used in many studies into volatiles in oils (Benincasa et al 2003;Cecchi and Alfei 2013;Wei et al 2015). HSSE is used for extracting volatile compounds from gaseous and aqueous phases (known as stir-bar sorptive extraction, SBSE) with the use of a stir-bar, usually coated with adsorbents such as polydimethylsiloxane (PDMS) (Sánchez-Rojas et al 2009). The static and dynamic headspace extraction techniques are simple and robust methods, but-compared with other solventless methods-SHS has lower sensitivity (Wenzl and Lankmayr 2002).…”

Principais técnicas de preparo de amostra para a determinação de resíduos de agrotóxicos em água por cromatografia líquida com detecção por arranjo de diodos e por espectrometria de massas

“…16 Estudos recentes correlacionam o coeficiente de partição com o coeficiente de distribuição octanol/ água (K ow ). 17 A DLLME foi desenvolvida em 2006 por Rezaee et al 18 como um avanço das técnicas de microextração em fase líquida. O método baseado no sistema ternário de solventes é uma miniaturização da LLE e usa microlitros de solvente extrator.…”
