SPME-GC-MSD for Determination of Nine Phenyl Compounds in Snow Water in Beijing China

Short Communication

Abstract

Solid phase microextraction (SPME) then capillary gas chromatography with mass spectrometric detection have been used for determination of nine phenyl compounds in snow water in Beijing City. Headspace extraction with a fiber coated with 100 µm PDMS was used to extract the compounds. Extraction and desorption times were optimized at 8 and 2 min, respectively. Relative standard deviation (RSD) of the analytical method was found to be less than 5%. The linear range was wide and limits of detection were less than 5 ng mL−1 for the nine target analytes. Several phenyl compounds at ng mL−1 levels were detected in snow samples in Beijing, indicating the corresponding air pollution.
