TL;DR: In this paper, the authors developed techniques for accurately and precisely measuring samples containing less than a few hundred micrograms of carbon, using a compact AMS system (NEC 0.5 MV 1.5SDH-1).

TL;DR: In this article, the authors present a brief discussion of sample preparation procedures at the Keck Carbon Cycle Accelerator Mass Spectrometer (KCCAMS), University of California, Irvine, and a systematic investigation of the use of Mg(ClO (sub 4 ) (sub 2) as an absorptive water trap, replacing the standard dry ice/ethanol cold finger in graphite sample preparation.

TL;DR: Stuiver et al. as mentioned in this paper used radiocarbon (Δ14C) and stable isotope (δ18O and δ13C) records from a 323-year banded coral series collected from the southern Great Barrier Reef, Australia.

TL;DR: A new radiocarbon accelerator mass spectrometry (AMS) laboratory for carbon cycle studies has been established at the University of California, Irvine as mentioned in this paper, where the 0.5MV AMS system was installed in mid-2002 and has operated routinely since October of that year.

TL;DR: An isotopic portrait of carbon assimilation by the in situ, free-living microbial community, integrated over >50,000 L of seawater, implies that recent, photosynthetic carbon is not always the major carbon source supporting microbial community production in the mesopelagic realm.
