Questions and Answers

Which method is typically used for scanning in magnetic sector analysers?

  • Scanning is not used in magnetic sector analysers
  • Both voltage and magnetic scanning
  • Magnetic scanning (correct)
  • Voltage scanning

What happens to the relative abundances of ions in a mass spectrum when voltage scanning is used?

  • The relative abundances increase as the mass increases
  • The relative abundances decrease as the mass increases (correct)
  • The relative abundances are not affected by voltage scanning
  • The relative abundances remain constant

What is the purpose of the collector slit in a mass spectrometer?

  • To allow ions of all m/e values to pass through (correct)
  • To convert ions into electrons
  • To detect ions
  • To restrict the passage of ions based on their mass
