In a chromatographic analysis of low molecular weight alcohols, propanol elutes with a retention time of 10.4 min, methanol's retention time is 4.60 min., and the retention time for ethanol

is 6.3 min. The column's void (dead) time is 0.39 min. Assume the width of the ethanol peak at the base is 0.2 min, and for propanol 0.4 min (it's hard to see on the chromatogram). Column length: 30.0 cm Column diameter: 0.50 cm What is the retention factor for ethanol? What is the selectivity factor for the separation of ethanol and propanol? What is the expected resolution for the separation of ethanol and propanol? What is the column efficiency for propanol?
