| Abstract: | 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. |
