Precise and accurate quantitative 13C NMR with reduced experimental time
چکیده انگلیسی

In order to detect small variations in 13C isotopomers concentrations, high sensitivity, accuracy and precision have to be achieved. To assess such criteria, when using 13C NMR, 13C bi-labelled ethanol has been proposed as a molecular probe. Advantage has been taken of the pre-established structural relationship between the peak areas of the 13C NMR spectrum of this molecule, i.e. the ratio of signal areas is set to a fixed value. It is shown that the quality performance, required by quantitative 13C NMR spectroscopy, is not affected by a large reduction of the repetition delay using relaxation reagents.
