Abstract
To provide an analysis device capable of quantitatively measuring the concentration of a substance without diluting a sample containing the substance to be analyzed, detection portions (5) that detect the substance in different concentration ranges are formed in a plurality of minute flow paths (2), respectively, and the concentration of the substance to be detected can be obtained within a calibration range in any one of the detection portions (5).
Claims20
-35. (canceled)
An analysis device comprising:
- a plurality of first minute flow paths that connect an injection portion accommodating a fluid to be injected to a discharge portion discharging the fluid,
- wherein the plurality of first minute flow paths are connected to the single injection portion,
- wherein in each of the plurality of first minute flow paths, a first detection portion is provided between the injection portion and the discharge portion and a first preprocessing portion reducing a concentration of a substance in the fluid is further provided between the injection portion and the first detection portion,
- wherein a capture substance capturing a substance to be detected is disposed in the first detection portion,
- wherein a capture substance capturing a substance to be reduced is disposed in the first preprocessing portion,
- wherein substances to be detected in the first detection portions of the plurality of first minute flow paths are the same as each other,
- wherein the first detection portions in the plurality of first minute flow paths detect the substances in different concentration ranges, respectively, and
- wherein the substance to be detected is the same as the substance to be reduced.
5 more elements
An analysis device comprising:
- first and second minute flow paths that connect an injection portion accommodating a fluid to be injected to a discharge portion discharging the fluid,
- wherein the first and second minute flow paths are connected to the single injection portion,
- wherein first and second detection portions are provided in the first and second minute flow paths, respectively,
- wherein a first preprocessing portion reducing a concentration of a substance in the fluid is further provided in the first minute flow path between the injection portion and the first detection portion,
- wherein a first capture substance capturing a substance to be detected is disposed in the first detection portion,
- wherein a second capture substance capturing the substance to be detected is disposed in the second detection portion,
- wherein a capture substance capturing the substance to be reduced is disposed in the first preprocessing portion,
- wherein the substances to be detected in the first and second detection portions are the same as each other,
- wherein the first and second detection portions detect the substances in different concentration ranges, respectively, and
- wherein the substance to be detected is the same as the substance to be reduced.
7 more elements
The analysis method according to 52, further comprising:
- measuring whether the target substance is captured in each preprocessing portion, and determining, when a given amount of target substance is not captured in the preprocessing portion, that the analysis error occurs.
