| Description
| - A novel, simple, and inexpensive approach to sorptive extraction, which we call solvent in silicone tube extraction (SiSTEx), was applied to pesticide residue analysis and its effectiveness and efficiency were evaluated. In SiSTEx, which is a form of open tubular sorptive extraction, a piece of silicone tubing (4 cm long, 1.47 mm ID, 1.96 mm OD in this study) is attached to the cap of a 20 mL glass vial that contains the aqueous sample. The tubing has been plugged at the end dangling in the sample solution, and acetonitrile (e.g. 40 µL) is added by syringe to the inner tube volume through a septum in the cap. A stir bar is used to mix the sample for a certain time (e.g. 60 min), which allows chemicals to partition into the tubing where they diffuse across the silicone and partition into the acetonitrile. The partitioning into the silicone depends on polarity of the chemicals, with the nonpolar compounds accumulating most readily in the acetonitrile. The final extract is relatively clean of the mo

- Byl testován nový, levný a jednoduchý způsob extrakce pesticidů ze vzorků ovoce a zeleniny. Princip extrace byl založen na sorpci analytů do silikonové trubičky z které byly pesticidy zpětně desorbovány do acetonitrilu. Finální stanovení bylo provedeno pomocí plynové chromatografie s pulsním plamenofotometrickým detektorem. (cs)
