1. A particle analyzer comprising:

  • a sheath flow cell for converting a particle containing sample into a sample flow;

    a first light source for illuminating the sample flow by a continuous light;

    a light detecting element for detecting a light emitted from a particle illuminated by the first light source and for converting the light into a particle signal indicative of a characteristic of the particle;

    a second light source for illuminating the sample flow by a momentary light;

    an imaging device for capturing an image of a particle illuminated by the second light source; and

    an analyzing section for performing particle analysis by employing the particle signal and the image of the particle as analysis data for analyzing the particle; and

    an inhibiting section for inhibiting the analyzing section from employing, as the analysis data, the particle signal obtained when the second light source illuminates the sample flow.
