Objective The uncertainty of the determination of PAHs ( anthracene ) in rubber by gas chromatography -mass spectrometry were evaluated .The factors affecting the results were analyzed . Method The PAHs ( anthracene ) in rubber by gas chromatography -mass spectrometry were determined according to ZEK 01.4 -2008 testing and validation of Polycyclic Aromatic Hydrocarbons ( PAH) in the course of GS -Mark Certification . The uncertainty of the results were evaluated and analyzed.The factors affecting the results were analyzed .The components are counted and combined . Result The expanded uncertainty is U=5.7 mg/kg, the confidence probability is 95%.Conclusion The factors affecting the results were mainly from calibration curve .
