Stable Isotope Ratio Mass Spectrometer
How it works, etc..... (under development)
- generate and purify gas sample
- maintain very high vacuum in spectrometer
- introduce gas to ion source
- ionize gas molecules
- accelerate ionized molecules
- focus beam of accelerated ionized molecules
- separate ions by mass and charge with a magnetic-sector analyzer
- detect ion beams with Faraday cup collectors
- amplify and process signal
- switch between sample gas and standard gas
- calculate isotopic ratios
