Study Notes
Chromatography
- Chromatography separates components based on their different adsorption rates AND solubility in the solvent.
- Separation relies on a stationary phase (adsorbent) and a mobile phase (solvent).
- Different components of a sample travel at different rates, resulting in visible separation.
- An example of a chromatographic setup uses paper as the stationary phase.
- A sample is spotted at the bottom of the paper and a solvent is drawn up, carrying different components at different rates.
- The different components form distinct spots, allowing identification and analysis.
