Comparison of the Sensitivity of Solid Phase MicroExtraction (SPME) and Stir Bar Sorptive Extraction (SBSE) for the Determination of Polycyclic Aromatic Hydrocarbons (PAHs) in Water and Soil Samples

چکیده
Two extraction techniques that avoid solvent consumption and cut down the sample preparation to a minimum Solid Phase MicroExtraction (SPME) and Stir Bar Sorptive Extraction (SBSE) – were compared on the basis of their reproducibility and sensitivity for 16 US EPA PAH compounds. Theoretical calculations indicated nearly quantitative recovery of all compounds under consideration except naphthalene for SBSE (10 mm GERSTEL TWISTER, df = 0.5 mm) whereas for SPME (100 μm PDMS) only higher boiling compounds benz[a]anthracene to benzo[g,h,i]perylene will show quantitative recovery and naphthalene for example will show only 10 % recovery.

PAL SPME Arrow--evaluation of a novel solid-phase microextraction device for freely dissolved PAHs in water.
After more than 25 years, solid-phase microextraction (SPME) has gained widespread acceptance as a well-automatable and flexible microextraction technique, while its instrumental basis remained mostly unchanged. The novel PAL (Prep And Load solution) SPME Arrow combines the advantages of SPME with the benefits of extraction techniques providing larger sorption phase volumes such as stir bar sor...
متن کاملFast and sensitive environmental analysis utilizing microextraction in packed syringe online with gas chromatography-mass spectrometry: determination of polycyclic aromatic hydrocarbons in water.
A new sensitive, selective, fast and accurate technique for online sample preparation was developed. Microextraction in a packed syringe (MEPS) is a new miniaturised, solid-phase extraction (SPE) technique that can be connected online to GC or LC without any modifications. In MEPS approximately 1mg of the solid packing material is inserted into a syringe (100-250 ml) as a plug. Sample preparati...

Abstract Polycyclic aromatic hydrocarbons (PAHs) are classified as persistent and carcinogenic organic pollutants. PAHs contamination has been reported in water. Many of relevant regulatory bodies such as EU and EPA have regulated the limit levels for PAHs in drinking water. In this study, 13 priority polycyclic aromatic hydrocarbons (PAHs) were determined in tap water samples of Tehran and wat...
