Gas Chromatography is an analytical technique used to separate and identify chemical compounds in a mixture.Common detectors include Flame Ionization Detector (FID), Thermal Conductivity Detector (TCD), and Electron Capture Detector (ECD).Carrier Gas: An inert gas (like helium or nitrogen) carries the vaporized sample through the column.This technique relies on the distribution of sample components between two phases: the stationary phase and the mobil1.Separation: As the sample travels through the column, different components separate based on their interactions with the stationary phase and their boiling points.Detection: After separation, the components exit the column and are detected by a detector.The column is coated with a stationary phase that interacts with the sample components.2.3.4.5.e phase.

It is injected into a heated injection port where it is vaporized.
2. Carrier Gas: An inert gas (like helium or nitrogen) carries the vaporized sample through the column.
3. Column: The column is the heart of the GC system. It can be packed or capillary (open tubular). The column is coated with a stationary phase that interacts with the sample components.
4. Separation: As the sample travels through the column, different components separate based on their interactions with the stationary phase and their boiling points.
5. Detection: After separation, the components exit the column and are detected by a detector. Common detectors include Flame Ionization Detector (FID), Thermal Conductivity Detector (TCD), and Electron Capture Detector (ECD).
e phase. The stationary phase is a solid or liquid fixed inside a column, while the mobile phase is a gas that carries the sample through the column
