Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ¹⁵N Integrity of Nitrogen-Poor Samples. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.
