Continuous-flow isotope ratio mass spectrometry (CF-IRMS) has been shown to minimize sample preparation and reduce the sample size requirements and time for the determination of carbon and nitrogen. An inexpensive CF inlet was developed for the determination of the 18O isotopic abundance in CO2. Ini

## Abstract The geochemistry of multiply substituted isotopologues (‘clumped‐isotope’ geochemistry) examines the abundances in natural materials of molecules, formula units or moieties that contain more than one rare isotope (e.g. ^13^C^18^O^16^O, ^18^O^18^O, ^15^N~2~, ^13^C^18^O^16^O~2~^2−^).

## We present the analysis of the stable carbon isotope compositions of 14 individual N-pivaloyl-isopropyl (NPP) amino acid esters by gas chromatography-combustion isotope ratio mass spectrometry (GC-C-IRMS). The mean reproducibility of derivatization procedure and GC-C-IRMS analysis was 0.45‰ (ra
