Study Notes
Chromatography Basics
- The fluid that carries a mixture through a structure holding another material is called the mobile phase.
Types of Chromatography
- Chromatography enables the separation, identification, and purification of mixture components.
Chromatography Process
- In chromatography, a mobile phase carrying a mixture moves in contact with a selectively absorbent stationary phase.
Separation Basis
- The separation in chromatography is primarily dependent on the differential partitioning of components between the mobile and stationary phases.
Chromatography Terminology
- The collective term for a set of laboratory techniques for the separation of mixtures is chromatography.
Chromatography Column
- The number of theoretical plates in a chromatography column is described by the term "plate number" or "plate count".
Separation of Constituents
- The primary basis for the separation of constituents in chromatography is the differential partitioning of components between the mobile and stationary phases.
Chromatographic Methods
- Chromatography methods that involve a solid stationary phase and a liquid mobile phase are classified as liquid-solid chromatography.
Laboratory Techniques
- The collective term for a set of laboratory techniques for the separation of mixtures in chromatography is chromatography.
Component Analysis
- Chromatography enables the separation, identification, and purification of components of a mixture for qualitative and quantitative analysis.
