Description:
The development of robust sample preparation techniques for ocean science research has been a hallmark of
NOSAMS since its inception. Improvements to our standard methods include reducing the minimum size of the
samples we can analyze, building modular graphite reactors of different sizes that we can swap in and out
depending on our sample stream, and modifying our carbonate acidification methods to improve handling of the
smaller samples we now receive. A relatively new instrument, the Ramped PyrOx, which allows the separation
of organic matter into thermal fractions, has attracted much interest as a research and development tool. We will
also discuss our progress on incorporating a Picarro isotope analyzer into our sample preparation options.
