摘要
Element analyzer-Isotope Ratio Mass Spectrometer (EA-IRMS) technology was applied to determine organic carbon stable isotopes of marine sediment. Moreover, the precision and accuracy of the results for the national standard material of GBW 04408, international standard material of Urea and marine sediment sample of M01 were measured. The TOC contents from marine sediment samples ranged from 0.13‰ to 1.11‰, with δ13Corg values ranging from -25.29‰ to -22.30‰, which indicate the derivation of organic matter from mixed terrestrial and marine organic materials.
