| Abstract: | In this paper,the method for determination of C_4 plant sugar in honey is developed by Elemental Analysis-Isotope Ratio Mass Spectrometry(EA-IRMS).Further,the uncertainty measurement for this method is evaluated for the first time. The method of evaluation is achieved by analysis of the uncertainty sources arising from the procedure of analysis. |
