- 6.1: Basic Principles of Chromatography
- Chromatography is yet another technique for the analysis and separation of chemical mixtures. The technique is based on a polarity interplay between the sample and two other substances called the solid (or stationary) phase, and the mobile phase, which can be a liquid or a gas. As their names indicate, the stationary phase does not move, whereas the mobile phase flows across, or through the solid phase.
