Question

Which statement is NOT true for GC carrier gases? A)N₂,He,and H₂ are the most common carrier gases. B)Optimal linear velocity increases in the order N₂ < He < H₂. C)The fastest separations can be achieved with N₂ as carrier gas. D)N₂ gives a lower detection limit than He with a flame ionization detector. E)Helium is the most common carrier gas and is compatible with most detectors.

The statement "The fastest separations can be achieved with N₂ as carrier gas" is not true. The optimal linear velocity increases in the order N₂ < He < H₂, indicating that H₂ would give the fastest separations. Therefore, option C is not a true statement for GC carrier gases.
