Abstract: A heat retention start timing of each sample container is determined based on a room temperature detected by a room temperature sensor, and a starting temperature and an ending temperature of each sample at a time of programmed temperature analysis that are stored in an analysis condition storage section. Since cooling speed of each sample container varies depending on the room temperature, the cooling time (A12, B12, C12, . . . ) of each sample container may be predicted based on the ending temperature of each sample at the time of programmed temperature analysis, the starting temperature of a next sample at the time of the programmed temperature analysis, and the room temperature. By determining the heat retention start timing of each sample container according to the cooling time (A12, B12, C12, . . . ) of each sample container predicted in the above manner, a margin time (A13, B13, C13, . . . ) after the cooling time may be prevented from becoming unnecessarily long.
