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 …
Blank Assessment for Ultra-Small Radiocarbon Samples
The Keck Carbon Cycle AMS facility at the University of California, Irvine (KCCAMS/UCI) has developed protocols for analyzing radiocarbon in samples as small as ∼0.001 mg of carbon (C). Mass-balance background corrections for modern and 14 C-dead carbon contamination (MC and DC, respectively) can be assessed by measuring 14 C-free and modern standards, respectively, using the same sample processing techniques that are applied to unknown samples. …
Compound-Specific Radiocarbon Analyses of Phospholipid Fatty Acids and N -Alkanes in Ocean Sediments
We report compound-specific radiocarbon analyses of organic matter in ocean sediments from the northeast Pacific Ocean. Chemical extractions and a preparative capillary gas chromatograph (PCGC) were used to isolate phospholipid fatty acids (PLFA) and n -alkanes from 3 cores collected off the coast of California, USA. Mass of samples for accelerator mass spectrometry (AMS) 14 C analysis ranged from 13–100 μg C. PLFA extracted from anaerobic sedime…
