Zusammenfassung: | The invention relates to a method for testing gaseous pollutants through arrow-shaped solid-phase microextraction. The gaseous pollutant testing method comprises the following steps: firstly, aging an arrow-shaped solid-phase microextraction device; collecting gaseous pollutants; preparing a standard curve of the compound by using the standard substance; testing a compound standard curve by using gas chromatography and high-resolution mass spectrometry; testing by using gas chromatography and high-resolution mass spectrometry, and obtaining the content of the compound through a standard curve; generating standard gas with known concentration, and adsorbing at the same time; and carrying out arrow-shaped solid-phase microextraction test on the adsorbed standard gas by using gas chromatography and high-resolution mass spectrometry, and calculating the partition coefficient of the compound; substituting the content of the compound sampled by the arrow-shaped solid-phase microextraction device in the actual air e |
