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. WebbThe distinguishing features of this nitride–imide composite nitrogen carrier lie in: 1. the Mn nitride not only acts as a nitrogen carrier but also functions as a catalyst significantly enhancing the kinetics of N 2 fixation by hydride to form imide and the subsequent hydrogenation of the imide to ammonia and the hydride; and 2. the hydrides, on the other …
