More Information
Summary:An atomic absorption spectrophotometer (10) includes a furnace (2) that heats a sample, a heating power supply (4) that includes a transformer (4a) and supplies a current to the furnace (2), the transformer (4a) converting a voltage to be applied to the furnace (2), a measurement unit (3) that measures an absorbance of the sample heated by the furnace (2), and a controller (7) that controls the heating power supply (4) and the measurement unit (3). The controller (7) sets a temperature program of the furnace (2) according to a sample to be measured, predicts, from information of the set temperature program, an attained temperature of the transformer (4a) during a continuous measurement, and prompts a user to change the temperature program when the predicted attained temperature reaches a prescribed temperature.
