METHOD FOR PRODUCTION OF CHROMATOGRAPHY MEDIA |
摘要 |
The present invention relates to a method and means to produce chromatography media having improved pressure-flow properties. More closely, the invention relates to bimodal particle size distribution and the use of layer functionalization as means to change pressure-flow properties of chromatography media. The invention relates to a method for production of chromatography media having improved pressure-flow properties, comprising mixing large beads/particles, comprising an inner core and an outer functionalized shell/lid, with smaller beads/particles, wherein the ratio of the particle size of large and small beads: [D50V for large particles/D50V for small particles]>1.2, and wherein the volume ratio of large and small beads in the column: [Total volume of large beads/Total volume beads] is in the range 0.05-0.9. |
