      This two values define the molecular weight range for a column, and depend mainly on Vi. Tipically Vo ~ 35% of Vc. Vg ~ 20-30% of Vc. People sometimes call Vt the void volume; this comes from HPLC where Vi is very small. Test Vo with a very large solute that can not penetrate the pores (sometimes difficult).

      The adjusted retention time tR’ adjusts for the column void volume. Retention volume (VR):The volume of mobile phase required to elute a substance from the column. This is where Vm is the void volume, KD the distribution coefficient, and Vs the stationary phase volume. Stationary phase: The immobile phase involved in the chromatographic process.
