Stable Isotope Natural Gas Reference Materials

The U.S. Geological Survey has developed a suite of natural gas standards. These reference gases are the replacement for the prior standards maintained by the U.S. National Institute of Standards and Technology. Details regarding development of the HCG RMs are provided in USGS Scientific Investigations Report 2021-5136. The natural gas standards are intended to serve as the primary carbon and...

Comparison of δ13C analyses of individual foraminifer (Orbulina universa) shells by secondary ion mass spectrometry and gas source mass spectrometry

Rationale: The use of secondary ion mass spectrometry (SIMS) to perform micrometer-scale in situ carbon isotope (δ13C) analyses of shells of marine microfossils called planktic foraminifers holds promise to explore calcification and ecological processes. The potential of this technique, however, cannot be realized without comparison to traditional whole-shell δ13C values measured by gas source mas
