ATOMIC ABSORPTION SPECTROPHOTOMETER AND SIGNAL VOLTAGE OPTIMIZATION METHOD USED BY THE SAME

摘要

There are provided an atomic absorption spectrophotometer capable of effectively preventing saturation of a signal voltage of a detector at the time of measurement, and a signal voltage optimization method used by the same. Test measurement of a sample is performed in a state where a preset value is taken as a set value of the signal voltage of the detector. The set value of the signal voltage of the detector corresponding to the sample is optimized based on the signal voltage of the detector at the time of the test measurement of the sample. In this manner, by optimizing the set value of the signal voltage of the detector corresponding to the sample through test measurement using the actual sample, saturation of the signal voltage of the detector at the time of measurement may be effectively prevented.
