The relative selectivity of a chromatographic column for a pair of solutes is given by the selectivity factor.
Column Selectivity
The relative selectivity of a chromatographic column for a pair of solutes is given by the
selectivity factor,
α, which is defined as
The identities of the solutes
are defined such
that solute A always has
the smaller retention time.
Accordingly, the selectivity factor is equal
to 1 when the solutes elute with identical retention times, and is greater than 1 when tr,B
is greater than tr,A.
