A method based on isotope dilution-mass spectrometry was developed for the determination of nine cholesterol oxidation products in human plasma. The cholesterol oxidation products determined were cholest-5-ene-3 \(\beta, 7 \alpha\)-diol, cholest-5-ene- \(3 \beta, 7 \beta\)-diol ( \(7 \alpha\) - and

Stable isotopes are now increasingly used for the control of the origin or authenticity of food products. Among these techniques, the measurement of the 18 O content of organic compounds has rarely been carried out because of technical difficulties in the preparation and measurement of the samples.

A method for determining the rate of exchange of the carbonyl oxygen in ~-ketoglutarate using gas chromatography-mass spectrometry is described. The method is based on a new procedure for quenching the exchange reaction by rapid oxidative decarboxylation of the LYketoacid to the next lower homologou
