A method for measuring specific activities of 14C-labelled compounds by gas chromatography-mass spectrometry-computer system.
A method for measuring specific activities of 14C-labelled compounds by gas chromatography-mass spectrometry-computer system (GC-MS-CPU) was developed. This method was proved to provide practically precise and accurate specific activities of various 14C-labelled compounds with such merits as requirement of small amount of samples, being applicable to volatile compounds, and convenience. The C.V. percent obtained for tested compounds was within 3.9 and the reliable sensitivity should be over 37 MBq/mM (1 mCi/mM). This method was also useful for obtaining information on the labelling pattern and the synthetic procedures applied.
