Effect of Carrier Gas Viscosity on Linear Velocity

Chromatographic separations using capillary columns are achieved under constant-pressure conditions, as opposed to packed columns, which are usually operated in a flow-controlled mode. The magnitude of the pressure drop across a capillary column necessary to produce a given linear velocity is a function of the particular carrier [Pg.127]
