The double advantage of Centrifugal Partition Chromatography is that solvent consumption and purification process time are drastically reduced.
We work to identify the appropriate solvent and the hydrodynamic characterization of each stationary phase in order to optimize purification methods at the industrial scale. We use digital models to help transfer the process to the industrial scale and to ensure that the projected calculations are valid.
Our engineering and R&D services
