We present gas chromatographic/mass spectrometric and gas chromatographic/isotope ratio mass spectrometric assays of the 13C enrichment of plasma urea converted to its dimethylaminomethylene derivative. The limits of sensitivity of the two techniques are 0.2% and 0.02%, respectively. The techniques

Glutamine is an essential fuel for tissues with high rates of cell replication, such as enterocytes and lymphocytes. Infusion of 13C-labeled glutamine tracers allows for measurement of the rates of production, utilization and oxidation of glutamineÏs carbon skeleton in vivo. The use of this tracer,

## 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
