Summary
If a peak (j=2) moves along the time axis of a chromatogram with no change in the position τ1 of the other peak (j=1) or in areas A1 and A2, the optimum separation, Řs, is defined as the resolution Rs which provides the maximum information, called FUMI, among all possible positions τ2 of the peak (τ2≥τ1). This paper demonstrates that optimum separation, Řs, of chromatographic peaks critically depends on the peak areas. As the area ratio A2/A1 of overlapped peaks increases, greater separation (higher resolution Rs) is needed to obtain maximum information. The quantitative relationship between Řs and A2/A1 is derived by computer simulation.
