  • Patent number: 11656223
    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.

  • Publication number: 20230136424
    Abstract: Provided is a sample processing apparatus management system, sample processing apparatuses and a management apparatus, and a management method that can accurately and easily adjust the respective sample processing apparatuses irrespective of their individual differences. When abnormality has occurred in a sample analyzer, the sample analyzer requests approval for self-adjustment from a management server. The management server determines whether to permit performance of the self-adjustment, and when having determined to permit the self-adjustment, notifies the sample analyzer of the approval for the self-adjustment. When the approval for the self-adjustment has been notified of, the sample analyzer performs the self-adjustment.
