where
and
are the chemical amounts of the
analyte in the
micellar and aqueous phases, respectively,
is the
distribution
constant and
and
are the corresponding volumes of the phases.

in micellar electrokinetic chromatography
in micro-emulsion electrokinetic chromatography
can be
calculated directly from the migration times:
should not be confused with the retention factor (in
column chromatography)
.
However,
is analogous to
the mass distribution ratio (in chromatography).
