Give the principle of Gas Chromatography?

Question

Accepted Answer

Gas Chromatography is a technique used to separate and analyze volatile compounds in a mixture.

Gas Chromatography separates compounds based on their volatility and affinity for the stationary phase.
It involves the use of a carrier gas to carry the sample through a column packed with a stationary phase.
The compounds in the sample interact differently with the stationary phase, leading to separation.
The separated compounds are detected and quantified using a detector, such as a flame ionization detector or a mass spectrometer.
Gas Chromatography is widely used in various industries, including pharmaceuticals, environmental analysis, and forensic science.

Accepted Answer

the sample solution injected into the instrument enters a gas stream which transports the sample into a separation tube
