Chromatography properties capacity factor

Relationships such as Eqs. (45) and (46) have been utilized extensively in correlating solubility properties (such as gas/liquid and liquid/liquid partition coefficients), retention volumes in gas/solid chromatography, capacity factors in high-pressure liquid chromatography, etc.199 200 For instance, gas/liquid partition coefficients for each of 35 different liquid stationary phases were represented with R > 0.985.205 Other applications have been in biochemical and pharmacological areas,199 200 e.g., enzyme inhibition and pollutant effects. 

In chromatography, the retention factor, or, equivalently, the capacity factor, is used to characterize the chromatographic equilibrium properties of an analyte. The retention factor of an analyte, k, is usually derived to be the product of the column phase ratio, Vr/Ve, and the distribution coefficient of the analyte between the stationary phase and eluent phase, Ca,r/ca,e, eqn [24] ...
