  • Patent number: 10441917
    Abstract: Provided is a method for separating, from a raw gas containing a specific gas, the specific gas using a gas separation membrane module. The gas separation membrane module includes a housing and a gas separation membrane element enclosed in the housing. The gas separation membrane element includes a gas separation membrane including a hydrophilic resin composition layer for selectively allowing for permeation of the specific gas. The method includes the steps of: increasing pressure in an interior of the gas separation membrane module; increasing a temperature in the interior of the gas separation membrane module; and feeding a raw gas to the interior of the gas separation membrane module in that order.

  • Patent number: 9242206
    Abstract: In a gas separation apparatus that separates carbon dioxide and water vapor from a first mixture gas containing at least carbon dioxide, nitrogen and water vapor, the energy utilization efficiency thereof is improved. The gas separation apparatus is constructed to include a first separation membrane 33 and a second separation membrane 34 that are made of different materials. When the first mixture gas is supplied, the first separation membrane 33 separates a second mixture gas containing carbon dioxide and water vapor that permeate through the first separation membrane by allowing carbon dioxide and water vapor to permeate selectively. When the second mixture gas is supplied, the second separation membrane 34 separates water vapor that permeates through the second separation membrane 34 by allowing water vapor to permeate selectively.

  • Patent number: 8574896
    Abstract: The present invention provides a colorimetric method that can perform a simple and reliable analysis in a short time. The method includes transferring an electron from an analyte to a coloring reagent that produces color by reduction via a mediator by using an oxidoreductase; and performing qualitative or quantitative analysis of the analyte by measuring color produced in the coloring reagent. The enzyme reaction of this method is a single stage reaction, and the color production reaction occurs via the mediator. Therefore, the measurement can be performed in a short time. Since this reaction requires neither hydrogen peroxide nor oxygen, the measured values are highly reliable.

  • Publication number: 20060147343
    Abstract: The present invention relates to an analytical tool (1A) which includes a flow path (8A) for moving a sample, a sample introduction port (73A), and a liquid reservoir (7A) for reserving the sample to be introduced into the flow path (8A) The flow path (8A) and the liquid reservoir (7A) are configured to cause suction force to act on both the flow path and the liquid reservoir. The suction force to act on the liquid reservoir (7A) is smaller than the suction force to act on the flow path (8A). The sectional area of the liquid reservoir (7A) in a perpendicular direction which is perpendicular to the movement direction of the sample is set larger than the sectional area of the flow path (8A) in the perpendicular direction. Preferably, the capacity of the liquid reservoir (7A) is set larger than the capacity of the flow path (8A).

  • Publication number: 20050014213
    Abstract: The present invention provides a colorimetric method that can perform a simple and reliable analysis in a short time. An aqueous solution including a bipyridyl copper complex and glucose dehydrogenase is prepared. A filter paper is impregnated with the aqueous solution and dried. When a sample such as blood is applied to the filter paper, the bipyridyl copper complex produces reddish brown color in accordance with the glucose concentration, and the color produced in the complex is measured. This reaction is a single reaction and thus occurs in a short time (e.g., 5 seconds or less). Since this reaction requires neither hydrogen peroxide nor oxygen, the measured values are highly reliable.
