Now from the Plate Theory (See Plate Theory and Extensions),

 

where (Vr) is the retention volume of the solute,
and (n) is the column efficiency.

Thus, (16)

Now, also from the Plate theory,

Vr = Vo(1 + k') (17)

where (Vo) is the column dead volume,
and (k') is the capacity ratio of the solute.
