“…Polydimethylsiloxane (PDMS) is broadly used in SBSE as the coating since it is commercially available (Prieto et al 2010). However, introducing new coatings has been taken into consideration over the last few years (Jafari et al 2018a;Jillani et al 2018;Mollahosseini et al 2020;Taghvimi et al 2019). Among different methods to prepare coatings, electrospinning is one of the versatile, simple and cost-effective methods (Castro-Mayorga et al 2017;Cavaliere et al 2011).…”

A polyacrylonitrile (PAN)/polydimethylsiloxane (PDMS) coating was electrospun on the shaft of the mechanical stir bar sorptive extraction (MSBSE) setup. MSBSE equipped with the PAN/PDMS coating and coupled with gas chromatography/flame ionization detector (MSBSE-PAN/PDMS-GC/FID) was used to determine some polycyclic aromatic hydrocarbons (PAHs) in nonalcoholic beer samples. The effective parameters including extraction time, desorption time, stirring speed and sample volume were optimized by the response surface methodology (RSM) based on the central composite design (CCD). The optimum condition was obtained in 60 min of extraction time, 10 min of desorption time, 1300 rpm of stirring speed and 16 mL of sample volume. The calibration curves of PAHs were linear in the range 5-1000 ng mL -1 . The limit of detections (LODs) was in the range of 0.009-0.5 ng mL -1 and the limit of qualifications (LOQs) was varied between 0.03 and 1.5 ng mL -1 . The relative recoveries and enrichment factors were in the range of 94-98% and 117-126, respectively, and the relative standard deviations (RSDs) were below 11.4%.
