PURPOSE:To make it possible to continuously separate a large number of specimens by unmanned operation, by remarkably increasing a magnetic field gradient by separately mounting ferromagnetic bodies to a separation trough comprising a passage small in the thickness thereof as compared with width and length thereof and the passage. CONSTITUTION:The titled apparatus consists of a separation trough 6 comprising a passage sufficiently small in the thickness (t) thereof as compared with the width and length thereof, a means 11 for flowing a liquid to be separated to be said trough 6, ferromagnetic bodies 9a-9c and means 3a, 3b for imparting high intensity magnetic fields in a direction at right angles to the surface of the trough 6 to which said ferromagnetic bodies are arranged. Each of the aforementioned ferromagnetic bodies 9a-9c is provided to the surface of the aforementioned passage and extended to the width direction of the passage and has a minute width (w) while a large number of the ferromagnetic bodies are arranged so as to be magnetically separated to each other at predetermined intervals T in the longitudinal direction of the passage. By the above mentioned apparatus, a magnetic field gradient becomes large and the use of a magnetic field as an acting field is enabled and a large number of specimens are continuously separated as liquid chromatography by unmanned operation. |
