Abstract：The headspace gas chromatography（HS-GC） method for the determination of phenol，naphthalene and anthracene insolvent-based polyurethane waterproofing coatings was optimized，and the gas chromatography（GC） and gas chromatography-mass spectrometry（GC-MS）were developed simultaneously.The three methods were discussed.The contents of phenol，naphthalene and anthracene were determined by HS-GC，GC and GC-MS， respectively.The linear relationship，sensitivity，accuracyand precision were compared and analyzed.The results showthat the three methods can meet the analysis requirements.Among them，the GC method has the best linearity， precisionand accuracy;the sensitivity of GC-MS method was the highest.The comprehensive evaluation showed thatthe GC method omited the heating step of HS-GC method，and the analysis time was significantlyshortened. The GC-MS methodand HS-GC method are more suitable forthe detection of samples with very low content of phenol，naphthalene and anthracene due to their higher sensitivity.
