Extraneous Carbon Assessments in Radiocarbon Measurements of Black Carbon in Environmental Matrices
Extraneous carbon (C ex ) added during chemical processing and isolation of black carbon (BC) in environmental matrices was quantified to assess its impact on compound specific radiocarbon analysis (CSRA). Extraneous carbon is added during the multiple steps of BC extraction, such as incomplete removal of solvents, and carbon bleed from the gas chromatographic and cation columns. We use 2 methods to evaluate the size and Δ 14 C values of C ex in …
Total Uncertainty of Radiocarbon Measurements of Marine Dissolved Organic Carbon and Methodological Recommendations
We report results of duplicate measurements of dissolved organic carbon concentrations ([DOC] as μM) and Δ 14 C in seawater in order to assess the total uncertainty of reported [DOC] and Δ 14 C measurements via the UV oxidation method. In addition, pure International Atomic Energy Agency standards analyzed over a 4-yr period are evaluated. We find the total uncertainty of Δ 14 C measurements to be ±4.0. However, in samples that were thawed, subsa…
