Abstract: In detection of a test substance including a biomolecule by utilizing photocurrent detection of dye sensitization, disclosed is a detection method in which process of the photocurrent detection is carried out by using an electrolyte solution not necessarily requiring an organic solvent. By making the electrolyte medium an aqueous system not containing an organic solvent, not only its usability can be enhanced but also measurement values with less dispersion can be obtained. Therefore, detection of the test substance including a biomolecule by utilizing the photocurrent detection of dye sensitization according to the present invention is characterized by that the processes from a reaction process of a test substance till detection of the photocurrent are carried out in a single apparatus, and that process of the photocurrent detection is carried out by using an electrolyte solution not necessarily requiring an aprotic solvent.
Abstract translation: 通过利用染料敏化的光电流检测来检测包括生物分子的测试物质，公开了一种检测方法，其中通过使用不一定需要有机溶剂的电解质溶液来进行光电流检测。 通过使电解质介质不含有机溶剂的水系，不仅可以提高其使用性，而且可以获得具有较少分散性的测定值。 因此，通过利用根据本发明的染料敏化的光电流检测来检测包括生物分子的测试物质的特征在于，将测试物质的反应过程直到检测到光电流的过程在单个装置中进行， 并且通过使用不一定需要非质子溶剂的电解质溶液进行光电流检测的过程。

Abstract: A flush toilet has a reservoir tank, a toilet main unit, a water supply apparatus, a water discharge apparatus, and a control device for controlling flushing of the bowl portion of the toilet main unit; wherein this control device includes a time measurement device for measuring the time after the water discharge apparatus has been driven for a predetermined time to discharge flush water, until the water level rises from a dead water level inside the reservoir tank with the water discharge apparatus in an off state to a predetermined stopped water level prior to start of flush; and the driving time of the water discharge apparatus responsive to pressure losses in the toilet main unit is adjusted by comparing the water level rise time measured by the time measurement device with the water level rise time in a standard toilet.
