Edexcel IAL Chemistry AS 2.6 Mass spectrometry
Edexcel IAL Chemistry AS 2.6 Mass spectrometry
Order ionisation, acceleration, deflection and detection, then multiply each isotope mass by its abundance and use peak positions and heights in the conclusion.
How this is tested
- Order ionisation, acceleration, deflection and detection in a mass spectrometer.
- Calculate relative atomic mass from isotope masses and percentage abundances.
- Interpret mass-to-charge peaks and heights to deduce isotopic composition.
