PROBLEM TO BE SOLVED: To provide a quick and simple separation analysis method by using one separation column and one kind of eluate, concerning separation analysis of a trace quantity of anions and/or cations below 10 ppm coexisting in aqueous solution containing a high concentration of one or two or more substances selected from among a group comprising weak acids having an acid dissociation constant of 2 or more, sugars, alcohols and amino acids. SOLUTION: Concerning measurement of anions and/or cations in the aqueous solution containing one or two or more substances selected from among the group comprising weak acids having the acid dissociation constant of 2 or more, sugars, alcohols and amino acids, this separation analysis method of ions in a high-concentration sample is characterized by using a weakly acidic cation-exchange separation column and the eluate of a weak acid by ion chromatography.

PURPOSE:To prevent the reflection of light and to obtain good productivity by forming an antireflection layer consisting of a specific copolymer on one surface of a transparent thin film consisting of polyvinyl acetal. CONSTITUTION:The antireflection layer consisting of the copolymer of the perfluroalkyl (meth)acrylate monomer expressed by formula I and the hydroxyalkyl (meth)acrylate monomer which is expressed by formula II and has plural OH groups at the terminal or side chain formed on at least one surface of the transparent thin film consisting of the polyvinyl acetal. In the formula I, R denotes H or methyl group; R denotes the group expressed by (CH2)m(CF2)nF, where me, n respectively denote m=1 to 2, n=3 to 14 integers. In the formula II, R denotes H or methyl group; R denotes 3 to 5C alkyl group having 2 to 3 pieces of OH groups at the terminal or side chain. The antireflection layer maintains a low refractive index in this way and the expos ing time is shortened. The production efficiency is thus improved.

PURPOSE:To measure a minute amount ions present in aqueous solution highly sensitively in excellent reproducibility by joining reaction solution containing counter-ion exchangers in order to remove the counter ions in elution component and eluate efficiently. CONSTITUTION:Sample solution containing ions are made to pass through a separating column 4, and the ions are separated. Then, the ions are made to react with reaction solution containing counter-ion exchangers, whose molecular weight is one million or more or particle diameter is 1.0mum or less. The ions are measured with an electric-conductivity detector 6. The counte-ion exchanger is the ion exhanger having a cation exchange device for removing cations. For example, polymers, whose unit structure comprises low molecule electrolyte such as polystyrene sulfonic acid, polyvinyl sulfonic acid, polyacryl acid and lignin sulfonic acid, the ion exchanger having cation exchange group on the surface of bases such as styrene, divinylbenzene gel and polyacrylate gel and the like are listed.

Abstract:
PURPOSE:To make improvement in transparency to UV light and far UV light and definition by incorporating an alkali-soluble resin contg. an arom. group, and ammonia salt having the reactive group and a compd. having a photoreactive group or reactive group as essential components into the above compsn. CONSTITUTION:An alkyl compd. of 5 to 30C contg. >=1 azide groups or an alkyl compd. of 5 to 30C contg. >=1 epoxy group or double bonds and the alkali-soluble resin contg. the arom. group are incorporated as the essential components into this compsn. The dissolution inhibiting ability of the ammonium salt depends on the structure of this salt; the dissolution inhibiting ability is high as the chain length of the alkyl group is longer, i.e. as the number of the carbon atoms is larger. The dissolution inhibiting ability is higher as the number of the long chain alkyl groups is larger. Further, exposed parts are made insoluble in an alkaline developing soln. by convering the short chain alkyl ammonium salt to a long-chain alkyl ammonium salt by exposing in the case of the short chain of the alkyl group of the alkyl ammonium salt. Unexposed parts are not changed in the solubility and patterning is possible. The improvement in the transparency to the UV light and far UV light and the definition is made in this way.
