Study Notes
Gas Chromatography Fundamentals
- The stationary phase in gas chromatography is responsible for separating the components of a mixture based on their interactions with the stationary phase.
Carrier Gas
- The carrier gas, typically an inert gas such as helium, nitrogen, or argon, plays a crucial role in gas chromatography as it transports the sample through the column.
Sample Injection
- Injecting a vaporized sample onto the chromatographic column allows the components of the mixture to separate and interact with the stationary phase.
Analytical Usefulness
- The ability to separate, identify, and quantify the components of a mixture gives gas chromatography its analytical usefulness.
Types of Gas Chromatography
- Gas-liquid chromatography (GLC) involves a microscopic layer of liquid or polymer on an inert solid support inside a piece of glass or metal tubing called a column.
