摘要:
A dry type multilayer analysis element comprises at least one porous medium layer comprising a membrane filter, to which an antigen (or antibody) is immobilized, and at least one reagent layer through which a substance(s) which did not participate in an antigen-antibody reaction can permeate.The multilayer analysis element is effective for assaying components present in body fluids, blood, urine, etc., in a simple manner.
摘要:
An integrated material for chemical analysis comprising three or more reagent layer units on a support and a porous spreading layer, said units containing reagents for different chemical analyses and being proximately arranged on a support such that approximately equal portions thereof are within a spreading circle defined by the diffusion of a liquid sample as it passes through the porous spreading layer, and a method for analyzing blood using the same.

A multilayered integral chemical analysis element for the blood comprising a filter layer capable of removing formed components from the blood, a water-proof layer having at least one small opening therein, a porous spreading layer and a reagent layer laminated in this order.
摘要:
An integral multilayered element for the chemical analysis of the blood comprising a combination of a porous spreading layer, a reagent layer, and a radiation-blocking layer, said radiation-blocking layer being water-permeable and containing at least one elemental metal or an alloy thereof.
摘要:
A multilayer analysis sheet for analyzing liquid samples is described, comprising, in sequence, a light transmitting hydrophobic support having on one side thereof at least one layer containing at least one reagent in a binder and a liquid sample spreading layer made of fabric, which layers are laminated to form an integral unit together with the support, wherein said fabric has the ability to supply a liquid sample placed on the surface thereof to the reagent-containing layer at a substantially constant volume per unit area, which ability is conferred upon the fabric by rendering it hydrophilic; the multilayer analysis sheet can be economically manufactured without variations in quality, and improves the spreading capability of liquid samples.
摘要:
Process of producing aspirin-containing capsules which comprises (1) dispersing aspirin particles in a solution of a cellulose derivative in an organic solvent partially miscible with water; (2) adding the dispersion to an encapsulation medium comprising water containing organic solvent(s) partially miscible with water with or without aspirin; (3) stirring the mixture to form a fine dispersion of the aspirin; and (4) evaporating off the organic solvent to deposit the cellulose derivative around the aspirin particles.
摘要:
A method of using a chemical analysis slide comprising a slide frame and a sheet-like or film-like chemical analysis element for colorimetric determination of a specific component in an aqueous liquid sample, which comprisesapplying an aqueous liquid sample to the chemical analysis element, andcovering the upper face of the side of the slide frame to which the sample is applied with a sheet-like, plate-like or block or brick-like cover to thereby ensure a space between the chemical analysis element and the cover and to prevent evaporation of water or to control evaporation rate of water.
摘要:
An integrated material for chemically analyzing a liquid sample comprising a supporting plate having provided thereon two or more different analytical units each comprising a reagent layer and a porous spreading layer or a portion of a common porous spreading layer, the units being disposed such that at least a portion of the reagent layers are in contact with or in close proximity to one another with the porous spreading layer(s) of the units being commonly covered with a liquid sample delivering patch.
摘要:
A method for quantitative determination of bilirubin is disclosed. The method comprises bringing a bilirubin-containing aqueous liquid sample into contact with a hydrophobic bilirubin extracting composition containing a hydrophobic amine capable of extracting bilirubin. The amine extracts the bilirubin in said aqueous liquid sample. Photometry is then used to determine the concentration of bilirubin extracted with the bilirubin extracting composition. A device for use in this method is also disclosed. The device has a layer containing a hydrophobic bilirubin extracting composition containing a hydrophobic amine capable of extracting bilirubin.
摘要:
A multi-layer chemical analytical material comprising a support, a reagent layer on the support and a spreading layer on the reagent layer wherein the reagent layer is composed of a hydrophilic binder and fine hydrophobic particles dispersed in the hydrophilic binder, said hydrophobic particles containing a reagent capable of directly or indirectly reacting with the component being analyzed to produce a color change.
