Membrane inlet mass spectrometry method (REOX/MIMS) to measure 15N-nitrate in isotope-enrichment experiments

Using 15N stable isotope as a tracer to quantify N transformation rates in isotope-enrichment experiments improves understanding of the N cycle in various ecosystems. However, measuring 15N-nitrate (15NO3–) in small volumes of water for these experiments is a major challenge due to the inconvenience of preparing samples by traditional techniques. Lin et al. (2021) developed a ...

Spectrally accurate quantitative analysis of isotope-labeled compounds

Abstract Calculated profile mode mass spectrometry (MS) data are fitted to lineshape-calibrated liquid chromatography LC/MS data using a Multiple Linear Regression (MLR) model to quantitate the ...
