Abstract
A flowcell for containing sample solutions is surrounded by an electric heater which is then surrounded by an isothermal frame having a large heat capacity, and a Peltier element serving as a cooling source is coupled with the isothermal frame. A heat delaying plate is arranged between the flowcell and heater and a temperature sensor is arranged between the flowcell and the heat delaying plate. The Peltier element is controlled in such a manner that the temperature of the isothermal frame is maintained substantially at a constant temperature lower than a predetermined temperature at which the sample solution is to be kept. The heater is controlled in accordance with a difference between the temperature of the sample solution and the predetermined temperature.
