The mildew odor in drinking water was analyzed by headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME GC / MS), and the sampling conditions of 1 000 μm polydimethylsiloxane (PDMS) The results show that the factors such as sample concentration, adsorption and desorption time, stirring and salt addition will affect the analysis results.Using the above conditions to analyze, we get the satisfactory results.
