intraparticle volume of the column

in size-exclusion chromatography
symbol: $V_{\rm{i}}$
synonyms: intrastitial volume of the column, stationary mobile-phase volume
https://doi.org/10.1351/goldbook.11549
Volume of the mobile phase within the pores of the particles in the stationary phase.
Note: The retention time equivalent to \(V_{\rm{i}}\) is \(t_{\rm{i}}\) \[t_{\rm{i}} = \frac{V_{\rm{i}}}{F_{\rm{c}}}\]
