Abstract :
Under the cooperation of horizontal magnetic force and vertical gravitational force, liquid mixtures were separated into each component under controlled temperature. Two separating methods were adopted. On a surface of a smooth concave, in a helium-free superconducting magnet bore, a mixture of two organic compounds was separated into two phases. This is a kind of magneto-gravitational separation, and is named as concave method. On a surface of gradient steps from the horizon, in a helium-free superconducting magnet bore, a mixture of two organic compounds was set in the first trough, and temperature was controlled. Some part of the liquid climbed the first slope and reached to the top and went down to the second trough. However, the remaining part of the liquid did not climb and stayed at the first trough. Then some part of the liquid in the second trough climbed the second slope and reached to the third trough, and so on. As the consequence, the original liquid mixture was separated into different components. This is a kind of magneto-gravitational chromatography, and is named as up and down method. By using these two methods, it is possible to separate mixtures into nearly pure components.
