Abstract:
1. An analytical instrument for analyzing a target substance contained in a specimen flowed into a cell container by utilizing an oxidative color-developing agent and an oxidative enzyme reaction, the analytical instrument comprising: a cell container comprising an upper substrate and a lower substrate arranged to face each other, the upper and lower substrates interleaving a space in which the specimen is flowed, wherein at least a portion of the upper substrate and/or at least a portion of the lower substrate comprises a material that transmits light and oxygen to analyze the target substance; wherein an open inlet configured to allow the specimen to flow in by capillary force is formed in the cell container, and an air hole, configured to allow air from inside the cell container to flow out, is formed in the cell container at a site separated from the open inlet by the upper substrate and the lower substrate; and wherein the analytical instrument further comprises; a dry reagent layer applied to and dried on at least portions of a facing surface of the upper substrate and/or the lower substrate, the dry reagent layer being dissolved by the flowed specimen and comprising an oxidative enzyme and an oxidative color-developing agent; and a sealing member provided between the upper substrate and the lower substrate and opposite to the open inlet of the dry reagent layer to prevent a liquid containing the specimen from flowing out of the cell container, wherein the air hole and the dry reagent layer are separated by the sealing member.
