The retention time (tr) and peak width (w) for compounds A and B are given after chromatographic separation using five different experimental parameters.Which chromatographic separations achieved a resolution that is desirable for quantitative analysis?Separation 1:compound A: tr = 14.0 min; w = 5.0 mincompound B: tr = 17.0 min; w = 6.5 minSeparation 2:compound A: tr = 10.0 min; w = 3.0 mincompound B: tr = 19.0 min; w = 3.0 minSeparation 3:compound A: tr = 14.0 min; w = 4.0 mincompound B: tr = 1

Two components in an HPLC separation have retention times that differ by 15 s. The first peak elutes in 9.0 min and the peak widths are approximately equal. The dead time tM was 65 s. Use a spreadsheet to find the minimal number of theoretical plates needed to achieve the following resolution R, values: 0.50,0.75, 0.90,1.0,1.10,1.25,1.50,1.75,2.0,2.5 . How would the results change if peak 2 were twice as broad as peak 1 ? | Numerade
