| Definition | Instruments that measure isotopic ratios using an electron ionisation source. Atoms in purified samples are ionised using a beam of electrons under vacuum. Subsequently, ions are focused into a beam by an electromagnet and then separated into individual beams based on their mass/charge ratio. | ||
