The resolution of a elution is a quantitative measure of how well two elution peaks can be differentiated in a chromatographic separation. It is defined as the difference in retention times between the two peaks, divided by the combined widths of the elution peaks.
Where B is the species with the longer retention time, and tR and W are the retention time and elution peak width respectively. If the resolution is greater than one, the peaks can usually be differentiated successfully.
