The volume occupied by the mobile phase between the particles in the packed section
of a column. It is also called the interstitial volume or the void volume of the column.
In
liquid chromatography, the interparticle volume is equal to the mobile-phase hold-up volume
(
) in the ideal case, neglecting any extra-column volume. In gas
chromatography, the symbol
may be used for the interparticle volume of the column. In the ideal case, neglecting
any extra-column volume,
is equal to the corrected gas hold-up volume
(
).
