Helium Carrier Gas. Carrier gas is an inert gas used to carry samples Helium (He) nitrogen (N2) hydrogen (H2) and argon (Ar) are often used Helium and nitrogen are most commonly used and the use of helium is desirable when using a capillary column Which of the following is the disadvantage of helium which can be used as carrier gas in gas chromatography? Which of the following is the.
Gas chromatography often uses helium hydrogen and nitrogen as carrier gases The most common carrier gas is helium since it provides good separations is inert and is safe to use In recent years the availability of helium has decreased and its cost has increased significantly So it is necessary to choose a suitable substitution.
Converting GC Methods from Helium to Nitrogen Carrier …
