Abstract: The present subject matter describes system (100) for magnetic enrichment of magnetically marked analytes. The system has capture chip (102) comprising a sample chamber (104) for holding sample having magnetically marked analytes, and a recovery chamber (106) connected to the sample chamber by a channel (202). The volume of recovery chamber is smaller than volume of sample chamber (104). The system has magnetic arrangement (108) comprising a set of magnets (110) in which each two adjacent magnets have opposite polarities facing sample chamber. Set of magnets has dimensions that at least conform to coverage area of sample chamber. The magnetic arrangement also has at least one recovery magnet (112) having dimensions conforming to coverage area of recovery chamber and on alignment, the at least one recovery magnet (112) is at a distance farthest away from the recovery chamber. The system has a linear positioner (114) for moving the magnetic arrangement.
