Study Notes
Types of Chromatography
- Liquid Chromatography involves a liquid solvent (mobile phase) and a column of solid beads (stationary phase) to separate liquid samples.
- Gas Chromatography separates vaporized samples using a carrier gas (mobile phase) and a column of liquid or solid beads (stationary phase).
- Paper Chromatography separates dried liquid samples with a liquid solvent (mobile phase) and a paper strip (stationary phase).
- Thin-Layer Chromatography involves a liquid solvent (mobile phase) and a glass plate with a thin layer of alumina or silica gel (stationary phase) to separate dried liquid samples.
Principles of Paper Chromatography
- Capillary Action is the movement of liquid within porous materials due to adhesion, cohesion, and surface tension forces, allowing liquids to move up filter paper despite gravity.
- Solubility is the degree to which a material (solute) dissolves into a solvent, with like dissolving like, enabling separation of solutes through different solvent combinations.
- Separation of components in chromatography depends on solubility in the mobile phase and affinity to both the mobile phase and stationary phase.
