#SCPH05 I Biotechnology

Gel chromatography is used for hormone separation. A pilot-plant scale gel chromatography column packed with sephacryl resin is used to separate two hormones, A and B. The column is 5 cm in diameter and 30 cm in height: V, = 1.9x 10-4m3, Wr = 3x10-3m3 /kg dry sephacryl, ps =1.25 x 103 kg/m3 . The partition coefficients are kpA =0.38 and kpB= 0.15. If the eluting flow rate is 0.7 I/h, what is the retention time for each hormone?
