摘要:
A chemical analysis device has a motor, a holder disk to be rotated by the motor, a plurality of inspection cartridges, a penetrator for penetrating the inspection cartridges, a heater and a detector. The inspection cartridge has a substrate including containers formed as recesses and a flow path, and a cover is mounted on the substrate to cover the containers and flow path. By a centrifugal force generated by a rotation of the holder disk, a liquid is moved through the flow path from the container at a radially inner side with respect to a rotational axis to the container at a radially outer side with respect to the rotational axis.

A chemical analyzer has a rotatable holding disk, test cartridges disposed thereon, and a detector. The test cartridge includes a base plate having vessels and flow channels. The base plate is covered with a cover for covering the vessels and flow channels. The holding disk is rotated to generate centrifugal force, causing a fluid to be moved from one vessel at the inner peripheral side with respect to a rotation axis of the holding disk to another vessel at the outer peripheral side with respect to the rotation axis via the flow channel. In the test cartridge, at least one reagent port is formed in the base plate, and a closed vessel containing a reagent is placed in the reagent port. The closed vessel is a microcapsule, a plastic closed vessel, or a screw-in closed vessel, for example.

A chemical analysis apparatus comprises a motor, a holding disk that can be rotated by the motor, a plurality of examination cartridges arranged on the holding disk, a perforator that perforates the examination cartridges, a heating device, and a detection device. The examination cartridge comprises a substrate including a vessel and a flow channel, which are defined by recesses, and a cover that covers the vessel and the flow channel. A centrifugal force generated by rotation of the holding disk is made use of to move a solution from a vessel on an inner peripheral side relative to an axis of rotation to a vessel on an outer peripheral side relative to the axis of rotation through the flow channel.

An analysis cartridge for use in a chemical analysis device comprises a reagent cartridge having a plurality of reagent containers formed therein to be able to contain reagents, and a reaction cartridge connected to the reagent cartridge and having a reaction container formed therein. The reagent cartridge and the reaction cartridge are each made up of a base plate and a cover covering recesses formed in a surface of the base plate. Channels for interconnecting the plurality of reagent containers and the reaction container are formed in the reagent cartridge and the reaction cartridge. The channels are formed inside the base plates of the reagent cartridge and the reaction cartridge in their connected portions. The structure of the analysis cartridge for mixing and reacting a specimen and reagents can be simplified.
摘要:
The invention provides a chemical analysis apparatus which easily agitates and warms up. A chemical analysis apparatus has a motor, a retaining disc which can be rotated by the motor, a plurality of inspection cartridges which are arranged on the retaining disc, a punching machine for punching the inspection cartridges, a warming apparatus and a detection apparatus. The inspection cartridge includes a container formed by a concave portion and a base plate having a flow path. A cover covering the container and the flow path is installed to the base plate. A liquid solution is moved to the container in an outer peripheral side with respect to a rotation axis from the container in an inner peripheral side with respect to the rotation axis via the flow path, by utilizing a centrifugal force generated on the basis of the rotation of the retaining disc. The inspection cartridge is provided with an agitating means for agitating the liquid solution within the container and a warming means for warming up the liquid solution within the container.

摘要:
A chemical analyzing apparatus accommodates therein a structure for retaining a sample and reagents. A detecting mechanism detects the sample after reaction with a reagent. After or during extraction of a biological substance from the sample in the structure, a temperature of a fluid in a space around the structure is controlled to a value which is suitable for enzyme.
摘要:
At the time of analytical measurement of a sample by the fluorescence measuring device or the phosphorescence measuring device, both the optical path of exciting light emitted from the light source to the sample and the optical path of fluorescence or phosphorescence emitted from the sample to the detection unit are shut off. Both are shut off by one chopper.
摘要:
An analytic method uses a labeled antigen, labeled antibody, tracer, etc. in which a radio isotope, fluorescent dye, luminescent dye, enzyme, etc. is bonded to an antibody or an antigen bonded to a protein as an object of analysis for performing an assay of a trace amount of a substance such as a hormone, tumor marker, infective pathogen marker, infective antibody, etc., for blood, serum, plasma, or body fluid as a sample or specimen. The analysis is enabled at high sensitivity, with less generation of noises and at low background. When an assay is performed based on the antigen-antibody reaction for a sample in an analytic method by fluorometry or luminometry, detection or measurement of non-specific fluorescence or luminescence such as interference light is eliminated or removed effectively irrespective of the property of the sample or the level of the concentration of substances contained in the sample.
