What type of gases are used in chromatography?

helium is the main one

also hydrogen

Inert gas such as helium or an unreactivegas such as nitrogen is used 

Gases like Helium, Argon ,  Nitrogen

Inert gases that can "carry" the sample without effecting the results. Gases such as nitrogen, helium, argon, and hydrogen.

In gas chromatography, the mobile phase (or "moving phase") is a carrier gas, usually an inert gas such ashelium or an unreactive gas such as nitrogen.Helium remains the most commonly used carrier gas in about 90% of instruments although hydrogen is preferred for improved separations.

Inert gas such as helium or an nonreactive gas such as nitrogen are used as carrier gas in chromatography

Nitrogen,Helium Hytrogon commonly used in gas in chromatography

Generally Nobel gases are used.

Also Helium,Nitrogen,Argon,Hydrogen,Air.

Its depend on which Detector using.

Inert gases like Helium, Argon and Non reactive gases like Hydrogen, Nitrogen
