Webb17 sep. 2024 · If we put all of this together, nitrogen requires a slower linear velocity than helium, but a narrow ID column allows us to increase the linear velocity of the intended carrier gas. Nitrogen has an idealized linear velocity of about 12 cm/sec on a 0.25 mm ID column, but has an ideal linear velocity of about 15 cm/sec on a 0.10 mm ID column. WebbNitrogen is in high demand by soil microbes.
