Determination of polycyclic aromatic hydrocarbons (PAHs) from organic aerosols using hollow fiber micro - porous membrane liquid - liquid extraction (HF-MMLLE) followed by gas chromatography-mass spectrometry analysis.

Summary, in English

A method for determination of polycyclic aromatic hydrocarbons (PAHs) from aerosols was developed. Instead of conventionally used non-polar or slightly polar phenylmethylpolysiloxane column a highly polar, highly substituted, cyanopropyl column (VF-23 MS) was used for separation of PAHs. Based on hollow fiber micro-porous membrane liquid-liquid extraction (HF-MMLLE) a method was developed for sample clean up and pretreatment. An enrichment factor of 617-1022 was obtained with extraction efficiency 10.2-18.9% for different PAHs analyzed in this study. The optimized method was successfully applied to aerosol samples and limits of detection between 1.2pgm(-3) and 180pgm(-3) was obtained. Almost all PAHs were found in most of the aerosol samples.
