| Abstract: | According to National Measurement Technology Criterion (Evaluation and Expression of Uncertainty in Measurement), Dimethyl fumarate in leather and leather products were determined by ultrasonic extraction and GC-MS, the source of uncertainty in the whole process of measurement was analyzed.Each component of uncertainty is estimated and composed.The composed and expanded uncertainties were given. When the content of dimethyl fumarate was 0.3 mg/kg, the expanded uncertainty was 0.02 mg/kg. |
