The retention factor (or capacity factor), k of a compound is defined as k= ms/mm, that is by the ratio of the masses of the compound in equilibrium in the two phases. Show, from the information given in the corresponding chromatogram, that the expression used - k = (tr-tM)/tm - is equivalent to this. Remember that for a given compound the relation between the retention time tr, the time spent in the mobile phase tm (hold-up or dead time) and the time spent in the stationary phase ts, is as follows: tr=tM+ts
