## Abstract On‐line gas chromatography‐combustion‐isotope ratio mass spectrometry (GC‐C‐IRMS) is commonly used to measure isotopic ratios at natural abundance as well as for tracer studies in nutritional and medical research. However, high‐precision ^13^C isotopic enrichment can also be measured by
