RCMS: Scale distortion from pressure baselines as a source of inaccuracy in triple-isotope measurements
Laurence Y. Yeung, Justin A. Hayles, Huanting Hu, Jeanine L. Ash, and Tao Sun Rapid Comm. Mass Spectrom. (2018) doi: 10.1002/rcm.8247 Rationale: Isotope ratio measurements have become extremely precise in recent years, with many approaching parts‐per‐million (ppm) levels of precision. However, seemingly innocuous errors in signal baselines, which exist only when gas enters the instrument, […]
