    摘要: One object of the present invention is to produce a weakly acidic cation exchanger under mild conditions. Another object of the present invention is to produce a more firm weakly acidic cation exchange film. Still another object of the present invention is to provide a weakly acidic cation exchanger capable of realizing high-level separation of monovalent cation and simultaneously analyzing monovalent cation and divalent cation and also provide a chromatography column using the ion exchanger. In the production method of a weakly acidic cation exchanger of the invention, a solvent incapable of dissolving a polymer having a double bond within the molecule is used and the weakly acidic cation exchanger is produced by polymerization at temperature of 100° C. or less.

    摘要: Pretreatment is performed using a pretreatment cartridge for separating substances that is packed with a stationary phase that is coated on its surface with a polymer whose tendency to hydration will change within a temperature range of 0-80° C. and which is capable of changing the affinity between the substance to be separated and the surface of the stationary phase in response to the shrinkage or swelling of the polymer chain due to temperature change. By using this pretreatment cartridge for separating substances, a convenient operation will suffice for a sample solution to be reduced to a solution containing the substance that need be separated from the specimen. If this method of pretreatment is used, useful substances can be separated intact by merely changing the temperature and it becomes possible to perform the subsequent analyzing or fraction collecting operation efficiently.
