Study Notes
Purpose of Chromatography
- Chromatography is a separation technique used to identify and quantify components within a mixture.
Factors Influencing Retention Time
- Chromatographic retention time, the time it takes for a substance to travel through the system, is influenced by factors like the compound's properties, the stationary phase, and the mobile phase's flow rate.
- Factors that do NOT play a role: The volume of the sample introduced to the system.
Mobile Phase
- The mobile phase is a fluid (liquid or gas) that carries the sample through the chromatographic system.
Real-World Applications
-
Chromatography has various applications, including:
- Identifying substances in environmental samples, like water and soil testing.
- Analyzing medications for purity and potency.
- Examining complex mixtures, isolating and identifying specific components.
Gas Chromatography
- Gas chromatography (GC) utilizes a gas as the mobile phase.
