In the Loop: Continuous Chromatography for Chiral (and Other) Separations
May 2nd 2006With single-enantiomer separations dominating the blockbuster charts, simulated moving bed chromatography and other multicolumn continuous chromatographic processes offer a quick route to clinical trial materials, along with the resolution, economy, and scalability to support tons-per-year production.
An Approach Using Bezier Curves to Control pH and Decrease Enzyme Inactivity
May 2nd 2006Using Bezier curves, an experimental process controller has been developed for biosynthesis applications in which the inactivity of a pH-sensitive enzyme must be decreased. By taking into account various control scenarios of pH and growth rate, as well as the physical and chemical characteristics of the environment, a suitable human-machine interface can be developed.
