Study Notes
Chromatography Overview
- Chromatography is a technique used to separate mixtures into their individual components.
- It is widely utilized in laboratories for analyzing substances in chemistry, biology, and environmental science.
Inventor of Liquid Chromatography
- Martin and Synge are credited with inventing and naming liquid chromatography in the early 20th century.
Meaning of Chromatography
- The term 'chromatography' derives from the Greek words "chroma" (color) and "grapho" (to write), originally pertaining to color separation observed in the technique.
Substances Separated by Chromatography
- Various substances can be separated, including gases, liquids, and dissolved solids, such as organic compounds, amino acids, and carbohydrates.
Purpose of Chromatography
- The main purpose is to purify compounds, identify substances, and analyze mixtures for quality control and research.
Mobile Phase in Gas Chromatography
- The mobile phase in gas chromatography consists of an inert gas, commonly helium or nitrogen, that transports the sample through the system.
Effective Gas Chromatography Type
- The most useful type for separating gases such as methane (CH4) and carbon dioxide (CO2) is capillary gas chromatography.
Stationary Phase in Gas Liquid Chromatography (GLC)
- In GLC, the stationary phase is a liquid coated onto a solid support material that helps retain the sample components as they move through.
Affinity in Gas Solid Chromatography (GSC)
- In GSC, the affinity of solutes is towards the solid stationary phase, allowing for separation based on adsorption characteristics.
Mechanism of Separation in Gas Chromatography
- Separation of components in gas chromatography occurs due to differences in volatility and interaction with the stationary phase, leading to varied retention times.
