Reading a mass spectrum

Reading a mass spectrum

Mass spectrum with fragment peaks at 29 and 57, base peak at 43, and a molecular ion peak at 74.0732 labelled on axes of relative abundance and m/z

Mass spectrometry turns molecules into ions, separates them by mass-to-charge ratio, and plots a mass spectrum. The horizontal axis is m/zm/zm/z and the vertical axis is relative abundance.

Mass spectrometry Lesson

  1. A Level
  2. /Chemistry
  3. /Mass spectrometry

Step-by-step lessons on AQA A Level Chemistry Mass spectrometry. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
