    Abstract: A cartridge to be installed in a detection device for detecting light generated from a measurement sample containing a test substance is provided. The cartridge includes: a plurality of detection chambers fluidly isolated from each other and each receiving a measurement sample; and a transmission suppression unit provided between one detection chamber and another detection chamber of the plurality of detection chambers, and configured to suppress transmission of light generated from a measurement sample in the one detection chamber to the another detection chamber.

    Abstract: In a method of detecting a test substance, a test substance is detected using a sample analysis cartridge supplied with a sample. The sample analysis cartridge includes: a passage part having a gas-phase space; and liquid containers communicating with the passage part through openings. The liquid containers include: a first liquid container containing a first liquid containing magnetic particles; and a second liquid container containing a second liquid containing a labeled substance. The magnetic particles are sequentially transported to the liquid containers through the gas-phase space in the passage part. Thus, the magnetic particles carry a complex of the test substance and the labeled substance. The test substance is detected based on the labeled substance in the complex.

    Abstract: A thermal history detection label for detecting a thermal history over a temperature range to be monitored while suppressing an increase in label size is provided. The thermal history detection label is configured to detect a thermal history by the permeation of a molten permeating material into a permeation body, and the thermal history detection label includes a permeating material that integrally includes a first permeating material having a first melting point and a second permeating material having a second melting point higher than the first melting point, and a permeation body into which the permeating material permeates.

    Abstract: The present invention provides a cartridge, a detection method, and a detection device capable of stabilizing the liquid level of a sample accommodated in a chamber in a predetermined state. A cartridge 20, that is rotated around a rotating shaft 42 for detecting a target substance, is provided with a chamber 100 in which a sample containing a target substance is stored. The chamber 100 includes a first region 110 in which a sample is stored, a second region 120 disposed at a position closer to the rotating shaft 42 than the first region 110, and a protrusion 130 protruding from a position between the first region 110 and the second region 120 to the inner side of the chamber 100.
