Core idea of chromatography

Core idea of chromatography

Chromatography separates a mixture because each component has a different balance between two phases. The stationary phase stays still and is usually a solid, or a liquid supported on a solid. The mobile phase is the moving fluid, which may be a liquid or a gas.

Chromatography (A-level only) Lesson

  1. A Level
  2. /Chemistry
  3. /Chromatography (A-level only)

Step-by-step lessons covering AQA A Level Chemistry Chromatography (A-level only) for A Level Chemistry. Each lesson breaks down Chromatography (A-level only), then works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. 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.
