Definitions
- the present invention relates to a technique for adjusting a liquid component held in the analysis tool for the purpose of an analysis tool used for analyzing a sample.
- a method of analyzing a sample for example, there is a method in which a reaction solution obtained by reacting a sample with a reagent is analyzed by an optical method. Such an analysis is performed, for example, by mounting an analytical tool for sharing the reaction field with an analytical apparatus configured with an optical system capable of irradiating and receiving light (for example, see Japanese Patent Application Laid-Open No. H08-08279). 114539). This: ⁇ ⁇ ⁇ To reduce analysis errors and increase the reliability of analysis results, adjust the analytical tools (especially the reaction solution) so that the sample and reagent react at approximately the same temperature for each measurement. Is preferred.
- the reaction rate has a large temperature dependence, and thus the system is adjusted to, for example, ⁇ 0.c for the target 1 ⁇ 2.
- the analysis tool 9 is held on a heat block 91 having a larger heat capacity than the reaction solution 90, and the temperature of the heat block 91 is controlled.
- There is a method of adjusting the reaction mixture 90 see, for example, JP-A-9-189703 and JP-A-10-253536).
- the temperature of the reaction solution 90 is monitored by a £ g sensor 92 embedded in the heat block 91, and when the value of the reaction solution 90 becomes smaller than a predetermined value, the heat block 91 is heated and heated. Then, the reaction solution 90 is heated through the heat block 91. Also, as shown in FIG. 9B, there is a method in which the analysis tool 9 is held on a heating element 93 having high followability, and the " " -See 304269). Also in this method, the temperature of the reaction solution 90 is controlled by appropriately driving the heating element 93 according to the monitoring result by the temperature sensor 92.
- heat the reaction solution 90 Since it is necessary to heat or drive the heating element 93, there is a demerit that power consumption is large.
- a heating medium such as a heat block 91 or a heating element 93
- the volume of the reaction solution 90 is small as in a microdevice. Difficult to heat. Therefore, in order to raise the reaction liquid 90 with high responsiveness, it is necessary to make the force Q heat medium 91, 93 considerably larger than the area to be heated (the area immediately below the reaction liquid 90 in the figure). is there. Therefore, the amount of heat used to raise the temperature of the reaction solution 90 is smaller than the amount of heat transmitted from the caro heat medium 91, 93, and the energy use efficiency is reduced.
- the conventional temperature control method has disadvantages such as large power consumption and poor energy use efficiency. Therefore, it is difficult to apply the conventional adjustment method to an analyzer driven by an internal power source such as a small battery (for example, a battery commonly used in homes). Even when applied to an analyzer, the operating time of the analyzer becomes extremely short, which is not practical. On the other hand, in order to improve the shortening of the operation time, it is necessary to increase the capacity of the internal power supply. However, in this case, the miniaturization of the analyzer is hindered, and the portability is reduced. In addition, power may be supplied from an external power source, but at that age, an adapter is required to connect the analyzer to an external power source. Becomes difficult.
