| 摘要 |
The present invention relates to a technique for causing the temperature of a liquid component retained in an analytical tool ( 1 ) to be adjusted to a target temperature, wherein the analytical tool ( 1 ) is used for analyzing the sample. According to the present invention, the temperature of the liquid component ( 10 ) is raised by heating the liquid component utilizing light energy from a light source ( 23 ). The temperature raising of the liquid component may be performed by supplying the light energy directly to the liquid component. Alternatively, the temperature raising of the liquid component may be performed by thermal energy transferred from a temperature raise region adjacent to the liquid component to which the light energy supplied. Preferably, as the light source ( 23 ) for raising temperature, use may be made of a laser diode or a light-emitting diode.
