IUPAC - mean interstitial velocity of the carrier gas (M03779)

mean interstitial velocity of the carrier gas

in chromatography

https://doi.org/10.1351/goldbook.M03779

The interstitial velocity,

u

of the carrier gas multiplied by the pressure-gradient correction-factor,

j

\bar{u} = u j

\bar{u} = \frac{F j}{ε_{I}}

where

F

is the nominal linear flow,

ε_{I}

is the interstitial fraction.
