a) Graph of the effective saturation α_e vs. the saturation α for 1D separations (α_e,1D) and 2D separations (α_e,2D). b) Graph of the average minimum resolution $R_s^{\ast }$ vs. the effective saturation α_e for 1D separations ( $R_{s,1D}^{\ast }$) and 2D separations ( $R_{s,2D}^{\ast }$). c) Graph of the p/m̄ ratio vs. the effective saturation α_e for 1D separations (——; calculated from Eqs. 3 and 8, and Figure 1d) and unbounded 2D separations (- - -; calculated from Eqs. 7 and 9, and Figure 1d). d) As in c), but with α_e determined by $R_s^{\ast }=0.725$.
