Regulated Method For Separating A Mixture
Patent No. EP3710127 (titled "Regulated Method For Separating A Mixture") was filed by Novasep Process on Nov 16, 2018. The application was issued on Aug 20, 2025.
Patent Summary
A method for separating a mixture using a multi-column chromatography system cyclically performs raffinate collection, mixture injection, extract collection, and mobile phase injection. The system is divided into four areas: Area 1 (mobile phase injection to extract collection), Area 2 (extract collection to mixture injection), Area 3 (mixture injection to raffinate collection), and Area 4 (raffinate collection to mobile phase injection). The method determines a concentration-representative variable history at a system node, detects a single characteristic point within Area 1, Area 4, or their interface, and compares this point to a target position. To align the point with the target, the carrying volumes of Area 1 and/or Area 4 are adjusted, while maintaining the injected mobile phase volume within specified minimum and maximum limits.
