MODEL RELEASED. Carbon dioxide analysis. Scientist uses a mass spectrometer to analyse a sample of atmospheric carbon dioxide,a greenhouse gas that traps heat in the atmosphere. The mass spectromet- er ionises molecules in the gas & propels them in- to a beam which is deflected by a magnetic field. This separates the different atomic forms (iso- topes) of carbon & oxygen in the gas,because each isotope has a different charge-to-mass ratio. The relative numbers of each type of isotope reveals the source of the carbon dioxide,such as biological activity or the burning of fossil fuels.
