Abstract: Disclosed herein is a spectrophotometer. The spectrophotometer includes a CPU having a signal prediction part and a comparison/calculation part. The signal prediction part predicts the strength of an output signal from a photodetection unit during the next period based on the strength of the output signal from the photodetection unit. The comparison/calculation part compares a reference value, which defines the limit value of electrical current passing through a photomultiplier tube, of the strength of an output signal from an AD converter with a predicted value predicted by the signal prediction part. In a case where the predicted value exceeds the reference value, a voltage applied to the photomultiplier tube is calculated so that the strength of an output signal from the photodetection unit during the next period does not exceed the reference value. An applied voltage control part is configured to perform applied voltage control based on an applied voltage value calculated by the comparison/calculation part when the predicted value of the strength of an output signal from the photodetection unit during the next period exceeds the reference value.

Abstract: A spectrophotometer is provided capable of reducing the influence of the vibration as much as possible when a wavelength dispersion element is rotationally driven and capable of increasing the analysis accuracy. When a fluorescence signal is obtained from the fluorescence detector, the central control unit A/D converts the fluorescence signal at sampling intervals of T1 for vibration convergence determination, and provides the result data to the data processor (S1). At the timing of performing the vibration convergence determination (S2), the data processor performs a predetermined signal processing to the digital signals obtained (S3), and determines whether all the data that have been obtained within a given period of time from the latest data are equal to or smaller than a specified value (S4). If all the data are equal to or smaller than the specified value, it is determined that the diffraction grating's vibration is converged, and the vibration convergence determination operation is terminated. After that, the central control unit changes the A/D conversion sampling interval to the interval T2 for obtaining the analysis data, and performs a spectrofluorometric measurement.
