What is gas chromatography?

Question

Accepted Answer

Gas chromatography is a technique used to separate and analyze volatile compounds in a sample.

Gas chromatography involves the vaporization of a sample and its separation into individual components based on their affinity for a stationary phase.
It is commonly used in various industries, such as pharmaceuticals, environmental analysis, and food and beverage.
Gas chromatography can be used to identify and quantify compounds in complex mixtures, such as analyzing the composition of essential oils or detecting pollutants in air samples.
The technique relies on the principle of differential partitioning of compounds between a mobile phase (carrier gas) and a stationary phase (column).
The separated compounds are detected by a detector, such as a flame ionization detector or a mass spectrometer.
Gas chromatography provides high resolution and sensitivity, making it a valuable tool in quality control and research.
Example: Gas chromatography can be used to determine the alcohol content in a beverage or analyze the purity of a drug formulation.
