Question

Two components in an HPLC separation have retention times that
differ by 22 s. The first peak elutes in 10.5 min and the peak
widths are approximately equal. Use a spreadsheet to find the
minimum number of theoretical plates needed to achieve the
following resolution, Rs, values: 0.50, 0.75, 0.90, 1.0, 1.10, 1.25,
1.50, 1.75, 2.0, and 2.5. How would the results change if peak 2
were twice as broad as peak 1?
