However, this method is less accurate than the methods of
isotopic dilution (ID).
However, SUAC is not always available in sufficient quantities to enable detection by qualitative organic acid methods, and should be measured using a sensitive, stable
isotopic dilution MS method.
The technique of [sup.13]C
isotopic dilution demonstrated the trophic action of nucleotides in the liver, increasing its cell regeneration.
Stable
isotopic dilution analysis liquid chromatography with tandem mass spectrometric detection (LC-MS/MS) has been used for assay of 8-OxodG [18].
1993, Carleton & Martinez del Rio 2010) that allow discriminating the isotopic changes caused either by diet (
isotopic dilution through somatic growth) or by metabolic turnover.
Lean body mass was estimated based on the
isotopic dilution space, and fat mass was estimated as total body mass minus lean mass (Schoeller et al., 1986).
LGC was asked to provide an independent reference value for the proficiency testing samples using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) with
isotopic dilution (IDMS), which revealed a bias of over 20% in the consensus value.

isotopic dilution techniques.
As already mentioned, where the isotopically labeled form of MMA was available, measurements were made by
isotopic dilution strategy.
Two
isotopic dilution procedures have predominated studies examining the phytoavailablility of soil elements and, depending upon the matrix sampled, have been designated as E or L values.
