Preparative liquid chromatography, as an efficient separation method, has been widely used in the separation of biopharmaceutical and chemical synthetic drugs. The Sepfocus® modular preparative chromatography system enables process development from the laboratory to pilot scale production requirements, with automated control of all equipment components such as automatic sampling, fraction collection, and data collection all under the same chromatographic software, facilitating process development and optimization. At the same time, we can also provide customers with complete solutions for packing life testing.
