PURPOSE: To facilitate the separating operation of components of a liquid, by using a composition comprising a separation layer forming material and an organic gelatinizing agent. n CONSTITUTION: A separation layer forming material is selected from a group of silicon, polybutene chloride, polystyrene chloride, ester polyacrylate and a copolymer of α-olefin or styrene and α, β-insaturated diester. An organic gelatinizing agent employs a condensate of sorbitol and benzaldehyde. In addition, a liquid to be separated is serum or plasma. the specific gravity of the composition at 25°C is 1.035W1.060 and the viscosity is 200,000W2,000,000,000 cps. In this manner, when specified components are separated from other components coexisting in the liquid utilizing the specific gravity difference therebetween, a partition is provided between both the components thereby facilitating separating operation of both the components. n COPYRIGHT: (C)1987,JPO&Japio |
