Abstract
Efficiency maps are proposed as plots of the dependence of the peak width at half height Δ1/2 on the function of the sorbate retention factor, obtained from a corrected expression for the efficiency of chromatographic systems for liquid chromatography with the addition of a parameter that takes into account dynamic broadening factors according to the formula \(\Delta _{{1{\text{/}}2}}^{2} = {{a}^{2}} + {{b}^{2}}k(k + 1)\). The efficiency maps can be used to compare various chromatographic systems avoiding the need for an unreasonable choice of random specific conditions of chromatography over the entire range of mobile phase compositions. The efficiency maps are shown to be sensitive to sorbate retention mechanisms.
