What is the principle of Gas Chromatography ???

The analysis performed by a gas chromatograph is called gas chromatography. Principle of Gas Chromatography: The sample solution injected into the instrument enters a gas stream that transports the sample into a separator tube known as a “column”. (Helium or nitrogen is used as a so-called carrier gas.)

What is gas chromatography and how does it work?

Gas chromatography separates compounds in a mixture by injecting a gaseous or liquid sample into a mobile phase, commonly referred to as a carrier gas, and passing the gas through a stationary phase. The mobile phase is typically an inert gas or a non-reactive gas such as helium, argon, nitrogen, or hydrogen.
