Ratio of the distance travelled by the centre of the spot to the distance simultaneously
travelled by the mobile phase:
By definition the
values are always less than unity. They are usually given to two decimal places. In
order to simplify this presentation the
values may be used: they correspond to the
values multiplied by 100. Ideally,
values are identical to the
values used in
column chromatography.
