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

Of all the elements, hydrogen has the largest naturally occurring variations in the ratio of its stable isotopes (D/H). It is for this reason that there has been a strong desire to add hydrogen to the list of elements amenable to isotope ratio monitoring gas chromatography/mass spectrometry (irm-GC/
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 glutamineรs carbon skeleton in vivo. The use of this tracer,
## Abstract The ฮด ^13^C values of 26 varieties of Chinese pure singleโflower honeys, 323 census samples of six varieties of singleโflower honeys and one multiโflower honey as well as 20 888 commercial honey samples from 135 honeyโrelated enterprises in 25 provinces of China were analysed by stable
A continuous-flow pyrolysis interface for gas chromatography/isotope ratio mass spectrometry (GC/IRMS) has been developed for 2 H analysis of individual organic compounds. Pyrolysis of gas chromatographically separated fatty acid methyl esters is performed at 1200 ยฐC in an unpacked alumina tube to c
