Abstract:
An analytical separation was performed on an analytical J-type counter-current chromatography (CCC) instrument using a 5.4 ml column, with a 1 ml/min mobile phase flow rate. This separation had a resolution of 0.69 and was achieved in 10 min. The same separation was performed using two 2300 ml columns connected in series at a flow rate of 850 ml/min using a production scale J-type centrifuge. This production scale separation was also obtained in 10 min with a resolution of 0.71. This represents an 850 times increase in productivity. This paper presents these separations and the underlying scale up theory.
