11. However the process requires many chemical processing, chromatography and mass spectrometry . 12. Becchi and his colleagues say they can detect synthetic testosterone by mass spectrometry . 13. Mass spectrometry is used in tests for doping and illegal drugs, for example.14. They then analyzed the samples using gas chromatography and mass spectrometry . 15. Electromagnetic mass spectrometry was investigated for the separation of uranium isotopes. 16. Analytical measurements may be performed using gas or liquid chromatography-mass spectrometry . 17. IRMPD is most often used in Fourier transform ion cyclotron resonance mass spectrometry . 18. They also used an early form of mass spectrometry to study hydrogen discharges. 19. Certain types of mass spectrometry data are best represented as a mass chromatogram. 20. Tests performed via accelerator mass spectrometry also support the earlier dates.
