Mass Spectrometry of Carbon Isotope in the Honey and ItsProtein

Abstract

Abstract: This paper discusses the mass spectrometry of carbon isotopes used in analysis of honey and its protein, including the design of devices, the preparation of samples and the test of the method’s accuracy and repetition. In the determination of carbon dioxide, the precision of this instrument is around 0. 005‰, when SIRA is used in determination of honey and honey protein samples, the diviations are 0. 08‰ and 0. 14‰ respectively. The results indicats that this method is reliable in the analysis of carbon isotope ratios in the honey and its protein.
