One application of thermal ionization is thermal ionization mass spectrometry (TIMS). This method is widely used in radiometric dating, where the sample is ionized under vacuum. The ions being produced at the filament are focussed into an ion beam and then passed through a magnetic field to separate them by mass. The relative abundances of different isotopes can then be measured, yielding isotope ratios.
