본문내용

1. Purpose
• Learning the basic principle of chromatography (used to determine the makeup
of a mixed solution) and the concept of polarity through the separation of
pigments using normal and reversed-phase chromatography.
• Key concepts
- Chromatography • Partition Chromatography
• Thin-Layer Chromatography
• Normal-Phase Chromatography
• Reversed-Phase Chromatography
- Polarity
- Electronegativity

2. Theory
◇ Concepts of key words
- Chromatography : The collective term for a set of laboratory techniques for
the separation of mixtures
- Polarity : It refers to a separation of electric charge leading to a molecule
having an electric dipole
- Electronegativity : It is a chemical property that describes the ability of an atom
(or, more rarely, a functional group) to attract electrons
(or electron density) towards itself.

◇ Stages of Chromatography
- Stationary Phase: the substance is fixed in place for the chromatography
procedure
- Mobile Phase: the phase where the substance moves in a definite direction
