Abstract:
1. An emission spectrophotometer, for generating a pulse light emission by supplying an energy accumulated in an electricity accumulating and discharging unit to a gap between an electrode and a test material, the emission spectrophotometer comprising: a first detection unit, for detecting an energy charged to the electricity accumulating and discharging unit before the pulse light emission; and a second detection unit, for detecting an energy remaining in the electricity accumulating and discharging unit after the pulse light emission; a comparison unit, generating a comparison result according to a comparison between the charged energy, detected before the pulse light emission, and a first preset threshold, and a comparison between the remaining energy, detected after the pulse light emission, and a second preset threshold; an output circuit; and a data processing device, wherein the output circuit outputs the comparison result to the data processing device.
