What mass spectrometry measures

What mass spectrometry measures

Schematic of a time-of-flight mass spectrometer with vaporisation, ionisation, separation and detection labelled

A time-of-flight mass spectrometer turns a sample into positive ions and sorts them by their mass-to-charge ratio, m/zm/zm/z. Ions with lower m/zm/zm/z travel faster through the flight tube, so they reach the detector sooner.

Step-by-step lessons on Edexcel 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.
