Abstract: |
This paper established a method for evaluating uncertainty of BTEXs measurement in Ambient Air by Solid adsorption thermal desorption Gas Chromatography.The sources of uncertainty and main influential factors of uncertainty in the measurement process were analyzed and synthesized according to Evaluation and Expression of Uncertainty in Measurement(JJF 1059 1999),and the final expanded uncertainty was given. |
Key words: Uncertainty evaluation Solid adsorption/thermal desorption Gas chromatography BTEXs |
