    摘要: A measuring chip for an optical analyzer includes a translucent or transparent substrate 1, and a sample solution chamber S formed on a sulface of the translucent or transparent substrate 1. The sample solution chamber S has an inlet S.sub.1 for introducing a sample solution to be analyzed, and an outlet S.sub.2 for discharging the analyzed sample solution. The sample solution chamber S is formed so as to be filled with the sample solution between the inlet S.sub.1 and the vicinity of the outlet S.sub.2 by the capillary phenomenon. On the translucent or transparent substrate 1, an analyzing region 10 is formed by stacking a metal thin film 2 and an immobilizing film 3 for immobilizing a physiologically active substance 4. On the analyzing region 10, the sample solution chamber S is formed to obtain a measuring chip for an optical analyzer particularly utilizing the surface plasmon resonance (SPR). Thus. it, is possible to obtain a measuring chip for an optical analyzer, which can be easily handled and which can carry out an analysis using a small quantity of sample solution.

    摘要: Proposed is an efficient method for the preparation of vitreous hollow microspheres from particles of a vitreous volcanic deposit by a heat treatment to effect expansion of the particles by foaming. The inventive method comprises a step, prior to the heat treatment for expansion of the particles, in which the starting particles are dispersed in an aqueous medium containing aluminum sulfate and urea each in a specified concentration followed by a heating treatment of the dispersion so as to deposit a coating layer of aluminum hydroxide on the particle surface so that the efficiency of foaming can be greatly improved without the disadvantage of particle agglomeration.

    摘要: A manufacturing method for cellulose ether having a high degree of substitution characterized in that an etherifying agent represented by a general formula RCH.sub.2 X (where R is aromatic group, heterocyclic group, vinyl group or ethynyl group or the same group substituted and X is chlorine or bromine) is reacted with a uniform solution of cellulose acetate having a degree of substitution of 2.0 and over in an organic solvent in the presence of a base to manufacture a highly substituted cellulose ether having a degree of substitution of 2.0 and over per anhydrous glucose unit by a one stage reaction at a good yield.As a general method for manufacturing cellulose ether, a method for reacting an etherifying agent with alkali cellulose is now in use. For the general method, several improved methods have been proposed. However, it is difficult to manufacture cellulose ether having a degree of substitution of 2.5 and over by a one stage reaction using the general method. As manufacturing methods for cellulose ether other than the general method, a method for using a solvent-soluble cellulose derivative as the raw material and a method for using a special solvent in which cellulose is soluble were proposed. However, the former had a defect of a low yield and the latter had a defect of too long a reaction time.
