Biochemicals labelled with carbon‐14 and hydrogen‐3 have been examined for their specific radioactivity by field desorption mass spectrometry, and the data obtained are compared with those derived from the combined use of chromatographic methods and liquid scintillation counting. The special methodology, and the advantages and drawbacks of these quantitative mass spectrometric determinations are discussed. First data on the interlaboratory reproducibility of quantitative field desorption mass spectrometry are reported.
