A sample of urine was analysed by high-performance liquid chromatography (HPLC)
and found to contain a mixture of fenoprofen and ibuprofen. Fenoprofen eluted after 7 min 50 s with a peak width of 23 s and ibuprofen eluted after 8 min 10 s with a peak width of 24 s. An unretained component eluted after 54 s. Calculate the retention factor (k’) for both drugs and the resolution (R) between them.
