Substrate for sample analysis, sample analysis device, sample analysis system, and program for sample analysis system

A substrate for sample analysis, which involves transportation of a liquid through rotational motion, the substrate for sample analysis comprising a substrate including a rotation axis;

• a first chamber, which is positioned in the substrate and includes a first space configured to retain the liquid;
• a second chamber, which is positioned in the substrate and includes a second space configured to retain the liquid discharged from the first chamber;
• and a first flow passage, which is positioned in the substrate, includes a path configured to connect the first chamber and the second chamber to each other, and is capable of being filled with the liquid retained in the first space through a capillary phenomenon, wherein the first flow passage has a first opening and a second opening, the first opening and the second opening are connected to the first chamber and the second chamber, respectively, and the first opening is positioned on a side closer to the rotation axis than the second opening, wherein the first space includes a first region, which is connected to the first opening and includes a portion extending from the first opening toward a side farther from the rotation axis, wherein the first space of the first chamber has a capacity larger than a capacity of the first flow passages wherein the first flow passage includes a first portion having the first opening and a second portion having the second opening, and wherein the second passage chamber has a capillary force larger than a capillary force of the first portion, and wherein the substrate has a thickness, and the first portion has a depth in a direction of the thickness of the substrate, the second portion has a depth in the direction of the thickness of the substrate, and the depth of the second portion is less than the depth of the first portion.
