Abstract:
1. A spectrometer apparatus comprising: a continuous wave laser irradiating part configured to irradiate a continuous wave laser to introduced particles; a scattering light measuring part configured to measure a scattering light emitted from the particles due to the continuous wave laser, wherein the scattering light measuring part comprises a triggering signal generator configured to generate a triggering signal if the voltage value calculated in the oscilloscope within the scattering light measuring part is greater than a preset voltage value or equal to the preset voltage value; a pulse laser irradiating part configured to receive the triggering signal to irradiate a pulse laser to the particles, wherein, a spectral analysis part configured to measure an emission light generated from the particles due to the pulse laser to analyze elements consisting of the particles, wherein a timing to apply the triggering signal to the pulse laser irradiating part is variably set according to a degree of the voltage value exceeding the preset voltage value, and wherein the timing of a particle causing a greater voltage value is set faster than the timing of a particle causing a less voltage value.
