Gas chromatography is a chromatographic technique used for the separation of
volatile compounds. The volatile compounds are the compounds that easily gets
vaporised at room temperature. Separation occurs based on the interaction of molecules with the mobile phase and the stationary phase. The less volatile molecules interact more with the stationary phase and moves slowly
where as more volatile molecules interact more with the mobile phase and moves fast. When the sample is detected the computer gives a peak with respect to the retention time of the sample.
The area under the peak gives information about the concentration of the sample.
