| Abstract: | The determination of cholesterol in human serum by isotope dilution /gas chromatography/mass spectrometry is briefly described . The method is based on the addition of a known weight of labeled cholesterol (3,4-~(13) C cholesterol) to a known weight of serum. Measurement of the intensity ratio of unlabeled to labeled ions was made by selected ion monitoring (SIM). The results of the CCQM - K6 key comparison are posted. |
