Mass spectrometry – UPSC Prelims

  • Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions.
  • The results are typically presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio.
  • It is an important tool and has helped win several Nobel Prizes.
  • It provides valuable information about the composition and structure of molecules.
  • It finds applications in drug testing to carbon dating.
  • Using mass spectrometry, researchers can ionise or break down the compound into simple ions and then identify the molecules based on their masses.
