Determination of furan in food samples using two solid phase microextraction fibers based on sol-gel technique with gas chromatography-flame ionisation detector

► HS-SPME based on sol-gel technology was proposed for determination of furan. ► The proposed method was applied for the extraction of furan in food samples. ► Two different SPME fibers, i.e. PEG and PEG/CNT, based on sol-gel were made. ► A comparative study of the PEG and PEG/CNTs fibers was done. ► This method has wide dynamic range and high sensitivity.
