An EA-IRMS method was developed for determination of element analysis stable isotope ratios of δ13C in cane sugar and beet sugar using liquid introduction. Results showed that this method was able to differentiate cane sugar from beet sugar according to their characteristic δ13C values. The δ13C values for beet sugar and cane sugar were between -25.48‰ and -24.05‰ and -11.87‰, respectively. The proposed method presented the benefits of accuracy and easy operation and the results were satisfactory.

Key words: element analysis stable isotope ratio mass spectrometry (EA-IRMS), δ13C, cane sugar, beet sugar
