Definition:
The ratio of the analytical concentration of a component in the stationary phase to its analytical concentration in the mobile phase. \[D_{\text{c}}=\frac{\text{amount of component}/\text{cm}^{3}\text{of stationary phase}}{\text{amount of component}/\text{cm}^{3}\text{of mobile phase}}\]
