mass spec-2.8

• why would there be a M + 1 peak?

  a 13 carbon isotope may be present.
• Mass spectrometry steps


  1. Ionisation

  2. Acceleration

  3. Deflection

  4. Detection
• Ionisation


  High energy electrons bombard the molecules of the sample and turn them into ions by knocking out one or more electrons
• why is the number of charges (z) usually 1 in a m/z ratio?

  usually 1 as 1 electron is knocked out from particle.
