Study Notes
Chromatography Basics
- Chromatography is a chemical method of separation.
Stationery Phase
- In column chromatography, the stationery phase is packed in a column.
Mobile Phase
- In chromatography, the mobile phase carries the sample through a layer containing the stationery phase.
Phases in Chromatography
- The mobile phase and stationery phase interact in chromatography, with solutes distributing between the two based on their relative tendency to associate with each phase.
Elution
- Elution is the process of displacing weakly bound analytes from the stationery phase.
Displacement
- Displacement is the process of displacing strongly bound analytes from the stationery phase by changing the physical or chemical nature of the mobile phase.
Forms of Chromatography
- Liquid Chromatography (LC) and Gas Chromatography (GC) are determined by the state of the mobile phase.
- In GC, the mobile phase is a gas.
Sample Components
- The components of a sample mixture in chromatography are referred to as solutes, analytes, or fractions.
Received Analyte
- The received analyte after elution in chromatography is referred to as the eluate.
