Problem- The resolution for two compounds in a chromatogram was measured to be R = 0.928. The retention times for each compounds compound are:
tR,A = 22.137 min
tR,B = 22.554 min
The dead time for the run was tM = 2.945 min. Determine the average number of theoretical plates in the column for these compounds.
