    • Contemporary 14C radiocarbon levels of oxygenated polybrominated diphenyl ethers (O-PBDEs) isolated in sponge–cyanobacteria associations 

      Guitart, Carlos; Slattery, Marc; Ankisetty, Sridevi; Radwan, Mohamed; Ross, Samir J.; Letcher, Robert J.; Reddy, Christopher M. (2010-12)
      Considerable debate surrounds the sources of oxygenated polybrominated diphenyl ethers (O-PBDEs) in wildlife as to whether they are naturally produced or result from anthropogenic industrial activities. Natural radiocarbon ...
    • Progress on a gas-accepting ion source for continuous-flow accelerator mass spectrometry 

      Roberts, Mark L.; Schneider, Robert J.; von Reden, Karl F.; Wills, J. S. C.; Han, Baoxi; Hayes, John M.; Rosenheim, Brad E.; Jenkins, William J. (2007-02)
      A gas-accepting microwave-plasma ion source is being developed for continuous-flow Accelerator Mass Spectrometry (AMS). Characteristics of the ion source will be presented. Schemes for connecting a gas or liquid chromatograph ...
